Answer: 15/16
Step-by-step explanation:
There will be 16 outcomes for 4 coins=2^4
Probability of only head is : P(C)=1/16
P(C) + P(C') = 1
P(C') = 1 - P(C)
P(C') = 1 - 1/16
Take the l.c.m
P(C') = (16-1) / 16
P(C') = 15/16
So the probability of getting at least 1 tail is 15/16
Answer:
The Correct Answer is: B
Step-by-step explanation:
Using proportions, it is found that $55.7 billion was donated to educational organizations.
<h3>What is a proportion?</h3>
A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct or inverse proportional, can be built to find the desired measures in the problem.
Of the $371 billion donated in total, 15% went to educational organizations, hence the amount is given by:
A = 0.15 x 371 = $55.7 billion.
Hence $55.7 billion was donated to educational organizations.
