Answer:
-$1.8
or loss of $1.8
Step-by-step explanation:
Given the following parameters, we have
The probability of winning $4 is 3/16
The probability of winning $7 is 2/16
The probability of losing $5 is 11/16
E(X) = (4 * 3/16) + (7 * 2/16) + (-5 * 11/16)
= 12/16 + 14/16 - 55/16
= -29/16
= -1.8
Hence, your expected net "winnings" would be -$1.8. That's an expected loss of $1.8.
Assuming that you need to place the numbers on a number line;
1) Convert all numbers in one form, be it fraction or decimals
16/4 = 4
-2.7 = -2.7
1.75 = 1.75
1/5 = 0.2
2) Draw a number line with zero in the middle and positive numbers going to the right. The negative numbers go on left.
3) Place the decimal/fraction numbers into the number line, using a constant interval.
Hope I helped :)
I believe 4(3 + x) and (3 + 3 +3 +3), there are four threes and 4(Three (3) + x) and there are three x's in (x + x + x + x).
