Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes.
We have the following sample space
That is, the possible outcomes.
I am going to call boys b and girls g
b - b - b
b - b - g
b - g - b
b - g - g
g - b - b
g - b - g
g - g - b
g - g - g
Total outcomes:
8 outcomes
What is the probability that they will have at least one boy and at least one girl?
Desired outcomes:
At least one boy and at least one girl
b - b - g
b - g - b
b - g - g
g - b - b
g - b - g
g - g - b
Six desired outcomes.
Probability
The correct answer is:
c. 0.75
Answer:
Example 11 answer = 12
Step-by-step explanation:
40, 36, 32, 28
is an arithmetic sequence.
The first term (a) is 40
The common difference (d) is -4
The formula for finding the nth term ( in an arithmetic sequence is;
= a + d(n - 1)
= 40 + -4(8 - 1)
= 40 - 28 = 12
