Answer:
0.683 = 68.3% probability that a randomly chosen doctor is in favor of the vaccine
Step-by-step explanation:
(a) What is the probability that a randomly chosen doctor is in favor of the vaccine
75% of 115/250 = 0.46(German).
60% of 65/250 = 0.26(French).
65% of 70/250 = 0.28(Englishmen). So

0.683 = 68.3% probability that a randomly chosen doctor is in favor of the vaccine
I think the first question is A)
The distance between the two buildings is 844.23 feet apart, we go this answer by simply applying the SOH CAH TOA method
<h3>Trigonometry</h3>
Given Data
- Height of Building A (Opp) = 400 feet
- Angle of Elevation θ = 35°
- Distance between the buildings Adj = ??
Applying the SOH CAH TOA Approach we have
Tan θ = Opp/Adj
Substituting our given data we have
Tan 35 = 400/x
0.4738 = 400/x
make x subject of the formula we have
x = 400/0.4738
x = 844.23 feet

Roll the dice 120 times
Number of outcomes from rolling the dice = 6
Probability of 4 falling in 1 roll = 1/6
Probability of the number of 4s in 120 rolls = 120 * 1/6
= 20 times
The probability that 4s falls in 120 dice rolls is 20 times.
