Question

Each turn in a game, you randomly draw a card from your deck and replace it. The table shows the number of times you draw each type of card.How many times can you expect to not draw a point card in 25 turns? Card type Frequency Point : 3 Recourse: 7 Defense : 5

Answer 1

Then, in 25 turns you expect to not draw a point card the next number of times:

`(4)/(5)\cdot25=20\text{ times}`
