Question

a container holds 15 pennies 8 nickels and 10 dimes. what is the probability you select a penny on your 1st draw?

Answer 1

The probability you select a penny on your 1st draw is:
`(15)/(33)`

Explanation:

We are given that a container holds 15 pennies 8 nickels and 10 dimes.

Total=15+8+10=33

We are asked to find the probability you select a penny on your 1st draw.

" The probability of an event is defined as the ratio of the total number of favourable outcomes to the total number of possible outcomes "

According to the given information we have:

The number of ways of selecting a penny is:
`\binom{15}{1}=15`

The total number of ways of choosing one amount is:
`\binom{33}{1}=33`

Hence the probability is:
`(15)/(33)`

Hence, the probability you select a penny on your 1st draw is
`(15)/(33)`.
