Outcome of coin toss = head, Tails
So, Probability of getting heads = Favorable outcome/ Total outcome
= 1/2
Now, Favorable outcome (of choosing a number less than 4) = 3
Total outcome = 10
So, probability = 3/10
Now, probability of getting heads and a number less than 4 = 1/2 × 3/10
= 3/20 or 0.15
Thus, probability of getting heads and a number less than 4 is 3/20 or 0.15
