You and your friend enter a drawing with 3 different prizes A total of 7 people entered the drawing and prizes are awarded randomly There are 210 ways to award class=

Respuesta :

The probability that you win first prize and your friend wins second

prize is 5/210

   

Step-by-step explanation:

Step 1 :

Total number of prizes awarded = 3

Number of people entering the draw = 7

Number of ways to award the prize = 210

We need to find the probability that we win the first and the second prize

Step 2 :

Out of the 3 prizes we need the first and the second. Hence the prize for the first and the second positions are fixed as we do not consider the remaining 5 people to win the prize here.

Hence the remaining number of people who can win the 3rd prize  = 5

The number of ways one of them wins the 3rd prize  = 5

The total number of ways = 210

Hence the probability of the first 2 prizes fixed and the remaining 3rd awarded to the rest of the 5 people is 5/210

Step 3 :

The required probability 5/210

Answer:5/210
