Answer:
B. 4/21
Step-by-step explanation:
⇒This question is on probability
⇒Number of boys=3
⇒Number of girls=4
⇒P(S)= 4+3=7
Probability for a girl to win is= 4/7
We have 3 awards a free movie ticket, a collectible poster, or a free popcorn
P(S)= 3
Probability of being awarded a free popcorn = 1/3
The probability that a girl will win free popcorn =
4/7 * 1/3 = 4/21

If Josie bought a mirror with 5 sides it would be a pentagon
we know it burns 3/4 of an inch in 1 hour, how about in 4 hours?
3/4 + 3/4 + 3/4 + 3/4, or simply....... ![\bf \cfrac{3}{4}\cdot 4\implies 3\cdot \cfrac{4}{4}\implies 3\cdot 1\implies 3](https://tex.z-dn.net/?f=%5Cbf%20%5Ccfrac%7B3%7D%7B4%7D%5Ccdot%204%5Cimplies%203%5Ccdot%20%5Ccfrac%7B4%7D%7B4%7D%5Cimplies%203%5Ccdot%201%5Cimplies%203)
so in 4 hours it has burned out 3 inches, it was originally 8 inches, 8 - 3 = 5.
