Question

A bag contains 200 pennies & 400 nickels. What is the probability of drawing a penny on the 1st try?

Answer 1

Given that the bag contains 200 pennies and 400 nickels. We are asked to find the probability of drawing a penny on the 1st try.

Step-by-step explanation

The probability of an event is given as;

`Pr(E)=\frac{numbe\text{r of favourable outcomes}}{number\text{ of total possible outcomes}}`

In this case, the number of favorable outcomes is the number of pennies while the total possible outcomes

is the sum of the coins in the bag.

Therefore, we will have

`\begin{gathered} Pr(\text{Pennies) = }(200)/(200+400) \\ =(200)/(600) \\ =(1)/(3) \end{gathered}`

Answer:

`(1)/(3)`
