Answer:
b. $28
Step-by-step explanation:
We have these following probabilities:
0.4 = 40% probability of $40
0.2 = 20% probability of $30
0.2 = 20% probability of $20
0.2 = 20% probability of $10
The expected value is:
We multiply each value by its probability. So
So the correct answer is:
3/5
The probability of an even number coming 6 times out of 10 is 6/10. Simplify to get 3/5
He got 5 right
10% = 0.1
50(0.1) = 5
