Answer:
Probability of event E = (4/10) = 0.40
Step-by-step explanation:
Note that n(E) is the number of outcomes in E
n(S) is the number of outcomes in S
And with each outcome having equal likelihood of occurring,
SetS = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10}.
n(S) = 10
Event E = {1, 4, 7, 9}.
n(E) = 4
Probability of event E = n(E)/n(S)
Probability of event E = (4/10) = 0.40
Hope this Helps!!
This question is incomplete, the complete question is;
You decide to record the hair colors of people leaving a lecture at your school. What is the probability that the next person who leaves the lecture will have blonde hair
?
Express your answer as a simplified fraction or a decimal rounded to four decimal places.
Blonde Red Brown Black Gray
31 25 18 40 42
Answer: the probability that the next person who leaves the lecture will have blonde hair is 0.1987
Step-by-step explanation:
Given that;
HAIR COLOR FREQUENCY
Blonde 31
Red 25
Brown 18
Black 40
Gray 42
Total 156
So
there were 156 people all together
and out of the 156, 31 of them were blonde.
now the probability that the next person who leaves the lecture will have blonde hair will be;
⇒ 31 / 156 = 0.1987
Therefore, the probability that the next person who leaves the lecture will have blonde hair is 0.1987
.24 = 24/100 = 12/50 = 6/25
