Question

Harpreet tosses two different coins simultaneously. Find the probability of getting exactly one head.​

Answer 1

$\huge\boxed{\underline{\mathcal{\red{H}\green{E}\orange{L}\purple{L}\pink{O}}}}$

Total possible outcomes= (H, H) (H, T) (T, H) (T, T)

Number of possible outcomes = 4

Total outcomes where harpreet get at least one head= (H, H) (H, T) (T, H) (T, T)

Number of outcomes where harpreet get at least one head= 3

P(Harpreet geta at least one head)

= Number of outcomes where harpreet get at least one head÷Number of possible outcomes

= 3/4

Answer 2

Step-by-step explanation:

Total possible outcomes= (H, H) (H, T) (T, H) (T, T)

Number of possible outcomes = 4

Total outcomes where harpreet get at least one head= (H, H) (H, T) (T, H) (T, T)

Number of outcomes where harpreet get at least one head= 3

P(Harpreet geta at least one head)

= Number of outcomes where harpreet get at least one head÷Number of possible outcomes

= 3/4
