A bag contains 5 blue marbles, 3 red marbles, and 2 yellow marbles. You select a marble at random. What is P(yellow)?
There are 10 marbles in total.
The probability of selecting a yellow marble is:
P(yellow) = Number of yellow marbles / Total number of marbles
P(yellow) = 2 / 10
P(yellow) = 0.2
Therefore, the probability of selecting a yellow marble is 0.2 or 20%.
A bag contains 5 blue marbles, 3 red marbles, and 2 yellow marbles. You select a marble at random. What is P(yellow)?
A. two over eight
B. four over five
C. one over five
A. two over eight
Multiple Choice
On the spinner below, what is P(odd)?
A circle is divided equally into eight sections.· One of the sections is labeled with a 1.
· One of the sections is labeled with a 2.
· Two of the sections are labeled with a 3.
· One of the sections is labeled with a 4.
· Two of the sections are labeled with a 5.
· One of the sections is labeled with a 6.
· The pointer originating from the middle of the circle is pointing at one of the sections labeled with a 3.
A. start fraction 5 over 8 end fraction
B. The fraction is 5 over 3.
C. one-half
There are a total of 8 sections on the spinner. Out of these 8 sections, there are 4 odd numbers - 1, 3, 3, and 5.
Therefore, the probability of landing on an odd number is:
P(odd) = Number of odd sections / Total number of sections
P(odd) = 4 / 8
P(odd) = 1/2
So, the answer is:
C. one-half
On the spinner below, what is P(multiple of 2)?
A circle is divided equally into eight sections.· One of the sections is labeled with a 1.
· Two of the sections are labeled with a 2.
· Two of the sections are labeled with a 3.
· One of the sections is labeled with a 4.
· One of the sections is labeled with a 5.
· One of the sections is labeled with a 6.
· The pointer originating from the middle of the circle is pointing at one of the sections labeled with a 3.
A. Start Fraction 4 over 4 End Fraction
B. one-half
C. start fraction 3 over 8 end fraction
Out of the 8 sections on the spinner, there are 2 sections labeled with a multiple of 2, which are 2 and 4.
Therefore, the probability of landing on a multiple of 2 is:
P(multiple of 2) = Number of sections labeled with a multiple of 2 / Total number of sections
P(multiple of 2) = 2 / 8
P(multiple of 2) = 1/4
So, the answer is:
A. Start Fraction 4 over 4 End Fraction
On the spinner below, what is P(red or blue)?
A circle is divided equally into eight sections. Three of the sections are blue, one is yellow, one is green, and three are red. An arrow originating from the center of the circle is pointing at one of the red sections .
A. start fraction 3 over 4 end fraction
B. eight-sixths
C. The fraction is 6 over 2.
Out of the 8 sections on the spinner, there are 3 blue sections and 3 red sections.
Therefore, the probability of landing on either red or blue is:
P(red or blue) = Number of red or blue sections / Total number of sections
P(red or blue) = 3 / 8 + 3/8
P(red or blue) = 6/8
P(red or blue) = 3/4
So, the answer is:
A. Start Fraction 3 over 4 End Fraction
On the spinner below, what is P(not purple)?
A circle is divided equally into eight sections. Three of the sections are blue, one is yellow, one is green, and three are red. An arrow originating from the center of the circle is pointing at one of the red sections .
A. 0
B. 1
C. one-half
