A) 47.70%
B) 52.30%
hope this is helpful!
At the beginning you have 10 balls, 5 of which are red. So, the chance of picking a red ball with the first pick is
![\dfrac{5}{10}=\dfrac{1}{2}](https://tex.z-dn.net/?f=%5Cdfrac%7B5%7D%7B10%7D%3D%5Cdfrac%7B1%7D%7B2%7D)
When it comes to the second pick, you have 9 balls (because you didn't replace the first red ball), 3 of which are blue. So, you pick a blue ball with the second pick with probability
![\dfrac{3}{9}=\dfrac{1}{3}](https://tex.z-dn.net/?f=%5Cdfrac%7B3%7D%7B9%7D%3D%5Cdfrac%7B1%7D%7B3%7D)
The two events will occur one after the other with the product of the probabilities:
![\dfrac{1}{2}\cdot\dfrac{1}{3}=\dfrac{1}{6}](https://tex.z-dn.net/?f=%5Cdfrac%7B1%7D%7B2%7D%5Ccdot%5Cdfrac%7B1%7D%7B3%7D%3D%5Cdfrac%7B1%7D%7B6%7D)

Below is the solution:
<span>sweeping the triangular end thru the length:
V = (1/2) (8ft) (7ft) (12ft)
V = </span><span>328 ft3 </span>
Answer:
10 + 16 = 26
16 + 26 = 42
26 + 42 = 68
(C) the next three terms are 26, 42, 68
