Your welcome :)
<u>Answer:</u>
The correct answer option is 43%.
<u>Step-by-step explanation:</u>
We are given that 70% of students have blue eyes, 45% have dark hair, and 30% have blue eyes and dark hair.
We are to find the probability of a student getting selected will have dark hair with blue eyes.
P(D|B) = P(D∩B) / P(B)
Substituting the given values in it to get:
P(D|B) = 0.3 / 0.7 = 0.428
Rounding it to the nearest whole percent we get:
0.428 × 100 = 42.8% ≈ 43%
B=s-15 b=boots, s=shoes
2b+3s=120
2(s-15)+3s=120
2s+3s-30=120
5s=150
s=30$. b=s-15
b=15$
A cuz a> b> c. If a=b and b=c, then a=c.
