Each letter of the English alphabet is written on a scrap piece of paper and put in a hat. P(j)
What type of probability is Illustrated and why.
19. probability of selecting a red marble)(probability of selecting a blue marble)
First, the probability of selecting a red marble.
Next, the probability of selecting a blue marble.
Multiply the probabilities together.
That is the probability for event a.
b.
Answer = (probability of selecting a red marble)(probability of selecting a blue marble)
First, the probability of selecting a red marble.
Next, the probability of selecting a blue marble WITH A RED MARBLE REMOVED.
Multiply the probabilities together.
That is the probability for event b.
c.
Obviously:
So the answer is no.
There are 4 red marbles.
There are 7 blue marbles.
There are 5 green marbles.
There are 16 marbles in total.
Would someone happen to have the answers for the Lesson 7: Probability Unit Test
Algebra Readiness (Pre-Algebra) B Unit 4: Probability test? I need to check my answers, I would really appreciate it.
Instead of putting abcd...... Just put the answer in word so if they do switch the order we can still answer it by the answer in words
20. total bands: 185 P(pink) = 95/185 = 19/37 P(brown) = 90/185 =18/37
A.P(pink) = 95/185 = 19/37 (in simplest form) theoretical probability of selecting pink rubber band.
B. P(brown) = 90/185 = 18/37 (in simplest form) theoretical probability of selecting brown rubber band.
C. You repeatedly choose a rubber band from the box, record the color, and put the rubber band back in the box. The results are shown in the table below. Find the experimental probability of each color based on the table.
Your welcome Guysss!!!!!!!!🙏🏽
Both these are wrong. Math tests always switch up the questions for everyone, but if you can say something like, “1. and the full answer”, and enough people do that everyone can get most of their questions.
ok guys, don't like something or dislike something unless you know for a fact that the answers are correct or not. (please and thank you)
Yeah what are the answer
I agree
