Question

roll a dice and find the probability of P(a composite number) P(a number less than 4)​

Answer 1

Answer:

in a dice number 4 and 6 are composite numbers

then the favourable outcomes is 2

Probability of composite numbers = 2/6

= 1/3

Possible Outcomes are 1,2,3,4,5 and 6

No. Of Outcomes less than 4 = 3

Probability of getting less than 4 = 3/6

= 1/2

Answer 2

Total possible outcomes = {1,2,3,4,5,6}
So number of elements in sample space = 6

i) Composite numbers are {4,6}
So probability of getting composite number = 2/6 = 1/3

ii) Number less than 4 = {1,2,3}
So probability of getting number less than 4= 3/6 = 1/2
