Question

Write your answer as a fraction in simplest form:
A number cube is rolled 37 times and the results are recorded as follows: 2 ones, 6
twos, 7 threes, 8 fours, 9 fives, and 5 sixes. What is the experimental probability of
rolling a number less than 4?

Answer 1

Add all the results up (37) and then add all the results less than 4, which are 2,6, and 7.  You will end up with 15. the experimental probability of rolling a  number less than 4 is 15/37. If you are counting 4, then the probability is 23/37...

Answer 2

$|\Omega|=37\\ |A|=15\\\\ P(A)=\dfrac{15}{37}\approx41\%$
