Answer:
3:2
Step-by-step explanation:
The ratio of boys to girls will be 12:8
But, this can be simplified, since both numbers are divisible by 4.
12/4 = 3
8/4 = 2
So, the simplified ratio of boys to girls is 3:2
I honestly don't know if this is right but it may make sense:
x is the event of picking up a rotten orange.
Probability that x is more than or equal to 1
= 1 - p(x=0)
so use binomialpdf on calculator
where trial is 4, p = 1/12(5/60), x = 0
1 - binoomialpdf(4, 1/12, 0)
and u get 0.294
