A.) $15 would seem like it would be right
Answer:
probability = 0.2517
Step-by-step explanation:
given data
boy kittens = 9
girl kittens = 6
choose kittens at random = 9
solution
total kitten are = 9 + 6 = 15
first we get here total no of probability that is
n(s) = 15 C 9
n(s) =
n(s) =5005
and
total way to chose 5 boy kittens is = 9 C 3
n(3) =
n(3) = 84
and
total way to chose 4 girl kittens is = 6 C 4
n(4) =
n(4) = 15
so
total way to chose 5 boy kittens and 4 girl kittens is
total way = 84 ×15 = 1260
so probability that the director chooses 5 boy kittens and 4 girl kittens is
probability =
probability = 0.2517
Answer:
225 students scored 65 or better and 75 students scored 88 or better.
Step-by-step explanation:
We are given that The five-number summary for the scores of 300 nursing students are given :
Minimum = 40
Median = 82
Maximum = 100
is the first quartile and is the median of the lower half of the data set. 25% of the numbers in the data set lie below and about 75% lie above .
is the third quartile and is the median of the upper half of the data set. 75% of the numbers in the data set lie below and about 25% lie above
i) .About how many students scored 65 or better?
Since we know that 75% lie above .
So, Number of students scored 65 or better =
ii)About how many students scored 88 or better?
Since we know that 25% lie above
So, Number of students scored 88 or better =
Hence 225 students scored 65 or better and 75 students scored 88 or better.
