Answer:
The expected value is $4.35
Step-by-step explanation:
For us to calculate the expected value , we need to multiply each of the given probability by the individual payout value and add
So we have it as;
0.35(1) + 2(0.2) + 5(0.1) + 8(0.2) + 10(0.15)
= 0.35 + 0.4 + 0.5 + 1.6 + 1.5
= $4.35

Answer:
100
Step-by-step explanation:
Let the time at which the two friends are at the same distance be x. With this representation, the equation would be,
3x = 4(x - 5/60)
The value of x from the equation is 0.33, which has a units of hours. Since, we are in minutes.
minutes = (0.333)(60)
minutes = 20
Answer: 20 minutes
