Answer:
It will cost the school $60
Step-by-step explanation:
In order to find this, set up a proportion.
$18/15 dozen = $x/50 dozen
Now cross multiply to solve
50 * 18 = 15 * x
900 = 15x
60 = x
Answer:
50%
Step-by-step explanation:
Let :
Winter = W
Summer = S
P(W) = 0.85
P(S) = 0.65
Recall:
P(W u S) = p(W) + p(S) - p(W n S)
Since, none of them did not like both seasons, P(W u S) = 1
Hence,
1 = 0.85 + 0.65 - p(both)
p(both) = 0.85 + 0.65 - 1
p(both) = 1.50 - 1
p(both) = 0.5
Hence percentage who like both = 0.5 * 100% = 50%
Total = 16 marbles
R = 4
B = 7
G = 5
a)
P(R) = 4/17
with replacing it P(B) = 7/17
so
P(R, then B) = 4/17 x 7/17 = 28/289
b)
P(R) = 4/17
no replacing, P(B) = 7/16
so
P(R, then B) = 4/17 x 6/17 = 24/289
c)
The answers to parts a and b are not the same.
Part a (28/289) with replacing, the probability to select a red then blue is higher then part b (24/289)
