Question

two coins are tossed simultaneously find the probability that exactly two heads turn up​

Answer 1

Answer:

1/4

Step-by-step explanation:

p(e)= no of favourable outcomes/no of total outcomes

therefore p(e)=1/4

Answer 2

P(E) = $\dfrac{1}{4}$ or. 0.25

Step-by-step explanation:

When two coins are tossed simultaneously.

All possible outcomes are:

(H, H), (H, T), (T, H), (T, T)

Total number of possible outcomes = 4

Let E be the event of getting exactly two heads turn up​.

The favourable outcome is:

(H, H)

Number of favourable outcomes = 1

∴ P(E) = $\dfrac{Number of favorable outcomes}{Total number of possible outcomes}$

= $\dfrac{1}{4}$ or. 0.25

Thus, P(E) = $\dfrac{1}{4}$ or. 0.25
