Answer

Explanation:

Step1: Calculate probability of drawing 4

There are 8 cards numbered 1 - 8. The probability of drawing a 4 in a single draw is $\frac{1}{8}$ since there is 1 card numbered 4 out of 8 total cards.

Step2: Calculate expected number of times 4 is drawn

The class conducts 1000 trials. The expected number of times a 4 is drawn is the probability of drawing a 4 times the number of trials. So, $1000\times\frac{1}{8}=125$.

Answer:

125
