The jar starts out with 8 marbles in it. Five of them are red.
If you don't peek, the probability of drawing a red marble is
5/8 .
If you have already drawn a red marble on the first try, then
at that point, the jar has only 7 marbles in it, and three of them
are green. Now, for your second draw, if you don't peek, the
probability of drawing a green marble is
3/7 .
The probability of BOTH of those events being successful is
(5/8) x (3/7) = 15/56 = approx 26.79% .
Answer:
66%
Step-by-step explanation:
50 - 17 = 33, so that is the difference between the two numbers. Percent change is the change over the original, so 33/50. 33/50 equals 66/100, so the percent change is 66%
You can solve this problem with one variable, x.
If the helicopter flew 34 times on Friday, and an equal number of times on Saturday and Sunday, then you can use the equation:
34+2x=118
2x=84
x=42
The answer is B.
Hope this helps!
