0.125 = 12.5% probability that all three coins come up heads.
0.875 = 87.5% probability that there will be at least one tail.
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes.
Question a:
Considering H for heads, T for tails:
H - H - H
H - H - T
H - T - H
H - T - T
T - H - H
T - H - T
T - T - H
T - T - T
(b) What is the probability that all three coins come up heads?
One outcome(H - H - H) out of 8, so:

0.125 = 12.5% probability that all three coins come up heads.
Notice that the complement of the event "3 heads" is "at least one tail." Use this information to compute the probability that there will be at least one tail.
Sum of these probabilities is 100%, so:
1 - 0.125 = 0.875
0.875 = 87.5% probability that there will be at least one tail.
Number of parts of the drinks = 31+1 = 6
In a 30 quart mixture:-
amount of orange juice = 3/6 + 30 = 15 qrts
.... ... ... pineapple = 2/6 * 30 = 10 qrts
.... ......... ginger ale = 1/6 * 30 = 5 qrts

Answer:
2nd one
Step-by-step explanation:
it was 0⁰F at 6 pm to -4⁰F at 11pm to you go to the left 4 times from 0⁰F and between 11pm and 5am the temperature dropped by 6 degrees so you go the the right 6 times from -4 which is 2⁰F so the 2nd one represents the temperature at 5am Hope it helped
Answer:
y = -2x +20
6x - 5y = 12
Put the value of y in 2nd equation
6x - 5( -2x +20 ) = 12
6x +10x -40 = 12
16x = 12 +40
16x = 52
x = 13/4
Putting the value of x in equation 1
y = -2x +20
y = -2(13/4 ) +20
y = 27/2
