Answer:
The probability that the hail storm will happen on a Saturday is 0.1667.
Step-by-step explanation:
The month of June started on Friday.
Then June 2 is a Saturday.
Remaining 28 days.
Each week has 7 days.
There will be 4 full weeks for the month of June.
So there will be 4 more Saturdays.
Thus, there are a total of 5 Saturdays in the month of June.
Compute the probability that the hail storm will happen on a Saturday as follows:

Thus, the probability that the hail storm will happen on a Saturday is 0.1667.
Answer:
n= 21
c= 3x
Step-by-step explanation:
The expression is given as;
(3x⁷)⁴
Apply the brackets law of indices which states that :
If a term with a power is itself raised to a power then the powers are multiplied together
(xᵃ)ᵇ = xᵃˣᵇ
Applying the same;
(3x⁷)⁴ = 3x²¹
If 3x²¹ = c^n
Then n = 21
and
c= 3x
The answer is (x-3)(x-3).
