There are 87 green balls and 41 red balls in a bag. If one is randomly selected, what is the probability that it will be a green

garri49 [273]

Number of green balls = 87

Number of red balls = 41

So total number of balls = 128

Probability formula = number of events / number of possible outcomes.

So, the probability that a ball randomly selected will be a green ball will be

$\frac{87}{87+41}$

equals 0.6796875 converting to nearest hundredth as 0.68

Answer these In scientific notation with work shown, adding scientific notation.

vichka [17]

Answer:

1. $9.9 \times 10^{-1} + 5.2 \times 10^{-2} = 104.2 \times 10^{-2}$

2. $3.24 \times 10^{5} + 8.3 \times 10^{1} =32408.3 \times 10^{1}$

3. $1.24 \times 10^{0} + 5 \times 10^{-1} = 13.64 \times 10^{-1}$

Step-by-step explanation:

1) $9.9 \times 10^{-1} + 5.2 \times 10^{-2}$

Now, $9.9 \times 10^{-1}$ = $99 \times 10^{-2}$

So, $99 \times 10^{-2} + 5.2 \times 10^{-2}$ = $104.2 \times 10^{-2}$

2. $3.24 \times 10^{5} + 8.3 \times 10^{1}$

Now, $3.24 \times 10^{5}$ = $32400 \times 10^{1}$

So, $32400 \times 10^{1} + 8.3 \times 10^{1}$ = $32408.3 \times 10^{1}$

3. $1.24 \times 10^{0} + 5 \times 10^{-1}$

Now, $1.24 \times 10^{0}$ = $12.4 \times 10^{1-}$

So, $1.24 \times 10^{0} + 12.4 \times 10^{1-}$ = $13.64 \times 10^{-1}$
