Question

A coin is tossed then a number 1-10 is chosen at random what is the probability of getting heads then a number less than 4

Answer 1

The probability of getting heads on a coin toss is 0.5
The probability of choosing a number less than four is 3/10 (1,2,3)

Therefore, the probability of getting heads and choosing a number less than four is:
$= \frac{1}{2} (\frac{3}{10}) = \frac{3}{20} = 0.15$

Hope this helps!
