Answer:
16:40, 0.4
Step-by-step explanation:
experimental probability would be a ratio consisting of the number of times the coin lands on heads to the total number of times the coin is flipped so it would be 16 to 40 or simply 16:40
theoretical probability would be a way to show the likeliness of the coin landing on heads and can be found by dividing the number of flips that is expected to land heads up by the total number of flips so you divide 16 by 40 which equals 0.4

Answer:
<h3>7/10</h3>
Step-by-step explanation:
Using set notation;
Let n(U) be the total number of students in the school = 100%
Let n(M) be the percentage of male students in the school = 56%
Let n(A) be the percentage of students between the ages of 18 and 20 (A) in the school = 32%
Let n(M∩A) be the percentage of both male and between the ages of 18 and 20 = 26%
The n(MUA)' be the number of female students in the school
Using the formula to get n(MUA)
n(MUA) = n(M)+n(A)- n(M∩A)
n(MUA) = 56+32-26
n(MUA) = 62%
Also, n(U) = n(MUA)+n(MUA)'
100 = 62+n(MUA)'
n(MUA)' = 100-62
n(MUA)' = 38%
This means that there are 38% of students in the school.
The probability of choosing a random student who is a female or between the ages of 18 and 20 is expressed as;
P(F or A) = P(F)+P(A) (mutually exclusive event i.e both cannot occur at the same time)
P(F or A) = 38/100 + 32/100
P(F or A) = (38+32)/100
P(F or A) = 70/100
P(F or A) = 7/10
Hence the probability of choosing a random student who is a female or between the ages of 18 and 20 is 7/10.
