1. a standard number cube is rolled 180 times. Predict how many times a 3 or 5 will be the result.
31 times
60 times***
57 times
30 times
2. A number cube is rolled 360 times, and the results are recorded as follows: 61 ones, 26 twos, 36 threes, 76 fours, 73 fives, and 88 sixes. What is the experimental probability of rolling a 2 or a 3?
0.15
0.1
0.35***
0.65
3.A standard number cube with the numbers 1 through 6 is rolled. find the probability of rolling a number less than 3. find the probability of not rolling a number less that 3. answer choices
a. 1/3, 2/3***
b. 1/2, 1/2
c. 5/6, 1/2
d. 1/6, 5/6
I agree with you on 1 and 3. I don't know for number 2. Are they labeled correctly?
#2, there were 26 two's and 36 three's
experimental prob (2 OR 3)
= (26+36)/360 = .1722..
which is none of the given choices.
#3
correct
