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.
Explanation
The probability of an event is given as;
[tex]Pr(E)=\frac{numbe\text{r of favourable outcomes}}{number\text{ of total possible outcomes}}[/tex]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
[tex]\begin{gathered} Pr(\text{Pennies) = }\frac{200}{200+400} \\ =\frac{200}{600} \\ =\frac{1}{3} \end{gathered}[/tex]Answer:
[tex]\frac{1}{3}[/tex]
