A gambler is trying to determine whether or not to make a bet. If he bets and wins, he will profit $2000. If he bets and loses, he has to pay $300. The probability that he wins the bet is 15%. Find the gambler's expected value if he makes the bet.

The gambler's expected value if he makes the bet is $45.

Step-by-step explanation:

Expected value:

15% probability of a profit of $2000.

100 - 15 = 85% probability of having to pay $300, that is, a loss of $300.

The expected value is each outcome multiplied by it's probability, so:

The gambler's expected value if he makes the bet is $45.

to find the perimeter of the rectangle this is the expression:

x-9+x-9+3x-4+3x-4=138

if we simplify it:

8x-26=138

remember, 138 is what it all adds up to

the length is 11.5cm

the width is 57.5cm

the area is 661.25cm^2
