The probability that  among the 1st 3 person who bought a ticket ,only one person will win the jackpot is 2/5

Solution:

The probability of an event is given as:

$Probability = \frac{ \text{ number of favorable outcomes }}{ \text{ total number of possible outcomes }}$

From given,

It is known that 4 tickets among 10 tickets can win the jackpot

Find the probability that  among the 1st 3 person who bought a ticket ,only one person will win the jackpot

Total number of outcomes = 10

favorable outcomes = 4

Therefore,

$probability = \frac{4}{10}\\\\probability = \frac{2}{5}$

Thus probability that  among the 1st 3 person who bought a ticket ,only one person will win the jackpot is 2/5
