Answer:
5
Step-by-step explanation:
The nth term of a geometric series is:
a_n = a₁ (r)^(n-1)
where a₁ is the first term and r is the common ratio.
Here, we have:
40 = a₁ (r)^(4-1)
160 = a₁ (r)^(6-1)
40 = a₁ (r)^3
160 = a₁ (r)^5
If we divide the two equations:
4 = r^2
r = 2
Now substitute into either equation to find a₁:
40 = a₁ (2)^3
40 = 8 a₁
a₁ = 5

Answer:
The probability is 6.16%.
Step-by-step explanation:
Total number of donuts = 24
Number of jelly filled donuts = 2
Number of lemon filled donuts = 5
Number of custard filled donuts = 17
The probability of selecting a jelly-filled donut =
= 0.0833
And probability followed by custard-filled donut =
= 0.7391 (23 because you ate 1 donut already)
Hence, the required probability is :
or 6.156% ≈ 6.16%
