Question

what is the probablity of getting exactly two tails when two coins are tossed to gether?

Answer 1

Answer:

1/4

Step-by-step explanation:

We can solve the above question by listing out all the probable outcomes.

Taking heads as (H) and tails as (T), the outcomes are:

HH, TT, TH, HT

The desired outcome (TT) occurs 1 time out of 4 outcomes. So, it's probability is:

Probability = (Number Of Favourable Outcomes) / (Total Number Of Outcomes)

⇒ Probability of getting exactly 2 tails = 1/4

Hence, the probability of getting exactly 2 tails is 1/4. Hope it helps!
