In a sample of 800 adults, 242 said that they liked sugar cereals. Three adults are selected at random without replacement. Find the probability that all three like sugar cereals.

Step-by-step explanation:

Given

--- Population

--- those that liked sugar cereals

Required

Probability that three selected like sugar cereals

The probability that the first adult selected likes sugar cereals is:

The probability that the second adult selected likes sugar cereals is:

We subtracted 1 because it is a probability without replacement

Similarly:

The required probability is calculated as follows:

answer

a,b, and d

explanation

a reflection angle is more than

but less than;

an angle that measures

is a reflex angle.(true)

an angle that measures less than

is acute.(true)

provided we are considering angles greater or equal to zero.

an acute angle lies in the range.

an obtuse angle is less than 180° but more than 90°

an angle that measures 300° is obtuse (false)

an angle that measures 65° is an acute angle.(true)

27 +27 or 27times 2=54

the diffrence is 0
