Answer:
30
Step-by-step explanation:
The expected value is just the weighted average of how much one ticket wins. To calculate it, we need to find the probabilities of winning each dollar amount, multiply each probability with it's respective dollar amount, then find the sum.
Let's call the winnings from one ticket X:
P(X=30) = 4000/2000000 = 0.002
P(X=800) = 500/2000000 = 0.00025
P(X=1200000) = 1/2000000 = 0.0000005
E(X) = 30*P(X=30) + 800*P(X=800) + 1200000*P(X=1200000) = 0.06 + 0.2 + 0.6 = 0.86
The answer is $0.86
Answer: a) 792 ways b) 13⁷.
Step-by-step explanation:
Since we have given that
Number of apples to be given = 5
Number of bananas to be given = 7
Number of people = 12
So, Number of ways that each person gets a pieces of fruit is given by
b) If the number of people = 13
Number of apples to be given = 7
So, Number of ways would be
Hence, a) 792 ways b) 13⁷.
