Question

A game uses a special deck of 40 card number from 1 to 40. You draw a card from a stuffled deck. 1. What is the probability of drawing a card that is divisible by 2( explain your reasoning) 2. what is the probability of drawing a card that is divisible by 5. (explain your reasoning) 3. What is the probability of drawing a card that is divisible by 10. (explain your reasoning)

Answer 1

`\begin{gathered} 1.\text{the number of cards that are divisible by 2 (even) are }20 \\ thus,\text{ the probability is 20/40=0.5} \\ \\ 2.\text{ the number of cards divisible by 5 is 8} \\ \text{ thus the probability is 8/40=}0.2 \\ \\ 3.\text{ the number of cards divisible by 10 is 4} \\ \text{ the probability is 4/40=0.1} \end{gathered}`
