Answer 1

Three coins are tossed together. The probability of getting exactly two tails is `underlinebb(3/8)`.

Explanation:

For three fair coins there are 2³ = 8 equally likely outcomes. 

Exactly two tails occurs in 3 outcomes (HTT, THT, TTH).

So the probability = `"Favorable"/"Total"`

= `3/8`
