Below are the results of tossing a number cube 7 times. Find the experimental probability of tossing an even number.
6 4 3 2 5 3 3
A. start fraction 3 over 7 end fraction
B. start fraction 2 over 7 end fraction
C. one-half
D. start fraction 4 over 7 end fraction
There are 7 total outcomes, and out of those, 3 are even numbers (2, 4, 6). Therefore, the experimental probability of tossing an even number is:
Answer: A. start fraction 3 over 7 end fraction
How many different ways can a band teacher select the lead and co-lead trumpet player from a group of 12 trumpet players?
A. 132
B. 264
C. 312
D. 448
There are 12 choices for the lead trumpeter and 11 choices left for the co-lead trumpeter (since one person has already been chosen for the lead trumpet). However, the order in which they are chosen does not matter, so we must divide by the number of ways to arrange 2 people, which is 2. Therefore, the total number of ways to select the lead and co-lead trumpet player is:
Answer: B. 264
To find the experimental probability of tossing an even number, we need to determine how many even numbers were obtained in the given data.
Looking at the results: 6 4 3 2 5 3 3
Out of the 7 numbers tossed, there are 3 even numbers (6, 4, and 2).
Therefore, the experimental probability of tossing an even number is:
3/7
So the answer is:
A. start fraction 3 over 7 end fraction
To find the experimental probability of tossing an even number, we need to determine how many times an even number was rolled in the given 7 trials.
Looking at the results, we can see that the even numbers rolled were 6, 4, and 2.
So, the experimental probability of tossing an even number is calculated by dividing the number of successful outcomes (even numbers rolled) by the total number of trials (7).
Number of successful outcomes: 3
Total number of trials: 7
Experimental probability = Number of successful outcomes / Total number of trials
Experimental probability = 3 / 7
Therefore, the experimental probability of tossing an even number is 3/7, which is represented as answer choice A.
