Expected number of wins=number of plays times the probability of winning
w=20(14.5/100)
w=20(0.145)
w=2.9
w≈3
So you would expect to win 3 times out of 20 attempts (rounded to the nearest whole number of wins)
Answer:
20991
Step-by-step explanation:
Yes
[5.5+(-2.3)] can be rearranged to be 5.5-2.3. It will be 3.2
(-5.5+2.3) can be rearranged to be 2.3-5.5. It will be -3.2
3.2-3.2=0
-15,-5,-2,1,3,8 it's pretty simple
