Question

The probability of flipping a fair coin and heads landing face up is 0.5. The probability of rolling a fair number cube, with sides numbered 1 through 6, and an odd number landing face up is 0.5. What is the probability of flipping heads or rolling an odd number?

Answer 1

Umm I would say that you do 0.5*0.5

so a 25% chance? Tell me if you think this is right or not, because if it's wrong I can try to help you again

Hope this helps :)

Answer 2

0.75

Explanation:

Given that The probability of flipping a fair coin and heads landing face up is 0.5. The probability of rolling a fair number cube, with sides numbered 1 through 6, and an odd number landing face up is 0.5.

We have to find out the probability of flipping heads or rolling an odd number

Let A = getting head: P(A) = 0.5

B = getting odd number P(B) = 0.5

Required prob = P(AUB) = P(A)+P(B)-P(AB)

P(AB) = 0.5 *0.5 = 0.25 since A and B are independent

Hence required probability

=0.5+0.5-0.25

=0.75
