Question

A fair dice is cast what's the probability that
(a)the result is 4
(b)the result is odd
Both Solve plz

​

Answer 1

Answer:

Let us mark the events:

A- An odd number comes up

B - A number greater than 4 comes up

We can see that the probability of the event A, P(A) = ½, since half of the numbers on a die are odd. We can also see that the P(B) = ⅓ since there are two numbers greater then 4 on the die. The probability of either one of those events, considering them being independent, is P(AB) = P(A) +P(B) - P(A)*P(B) which is 4/6. This is the lengthier way of doing that. You can also just count the number of positive outcomes and divide it by the total possible number of outcomes.

Answer 2

Explanation:

The probability of rolling a 2 on a 6-sided dice is 16 . The probability of rolling two 2s on two 6-sided die is, by the multiplication principle, 16×16=136
