Bag A contains 3 white marbles and 2 red marbles. Bag B contains 6 white marbles and 3 red marbles. A person draws
mr_godi [17]

Answer:

\frac{2}{5}

Step-by-step explanation:

Bag A:

White = 3

Total = 3 White + 2 Red = 5

Prob (white marble from A) = \frac{3}{5}

Bag B:

White = 6

Total = 6 White + 3 Red = 9

Prob (white marble from B) = \frac{6}{9}

Prob (white from Bag A and white from Bag B)

= Prob (white marble from A) x Prob (white marble from B)

= \frac{3}{5} x \frac{6}{9}

= \frac{2}{5}

(8CQ) Find the sum of the geometric series. <br> 20-10+5-5/2+...
Ivahew [28]

Answer:

b. \frac{40}{3}

Step-by-step explanation:

The given geometric series is;

20-10+5-\frac{5}{2}+...

The first term of this series is

a_1=20

The common ratio is

r=\frac{-10}{20}=-\frac{1}{2}

The sum to infinity of this series is

S_{\infty}=\frac{a_1}{1-r}

Substitute the given values to obtain;

S_{\infty}=\frac{20}{1--\frac{1}{2}}

This implies that;

S_{\infty}=\frac{20}{\frac{3}{2}}

S_{\infty}=\frac{40}{3}
