Answer:
Yes the probability of getting at least one airplane from two boxes is 3/4 which is greater than 0.5.
Step-by-step explanation:
The probability of getting at least one aeroplane is calculated by = 1 -(P(not aeroplane from 1st box) P (not aeroplane from 2nd box))
P(at least one aeroplane)= 1- {P(not aeroplane)P(not aeroplane)}
Suppose there is one helicopter and one aeroplane in each box so
P(at least one aeroplane)= 1- {(1/2) (1/2))}
P(at least one aeroplane)= 1- 1/4
P(at least one aeroplane)= 3/4 > 0.5
So the probability of getting at least one airplane from two boxes is 3/4 which is greater than 0.5
Answer:
d. a_n = 6n - 4.
Step-by-step explanation:
The common difference (d) is 8-2 = 14-8 = 20-14 = 26-20 = 6.
This is an Arithmetic Sequence with the first term (a1) is 2.
The general form of the explicit formula is a_n = a1 + d(n - 1) so this sequence has the formula:
a_n = 2 + 6(n - 1)
a_n = 2 + 6n - 6
a_n = 6n - 4.
