Question

o. In a college where boys and girls are in equal proportion, it was found that 10 out of 100
boys and 25 out of 100 girls were using the same brand of a two wheeler. If a student using
that was selected at random what is the probability of being a boy?​

Answer 1

Answer:

1/20

Step-by-step explanation:

As the number of boys is equal to girls the probability that it will be a boy is 1/2 but the proportion of boys having the bike are 1/10 hence the solution will be multiplication of the both.

• 1/2 *1\10 =1/20.
