Butoxors [25]

Answer:

72%

Step-by-step explanation:

A circuit contains two switches.

The first switch transmits messages correctly 80% of the time, then the probability that the message will be transmitted successfully through the first switch is

$p_1=0.8$

The second switch transmits messages correctly 90% of the time, then the probability that the message will be transmitted successfully through the second switch is

$p_2=0.9$

The probability that the message will be transmitted successfully through both switches is

$p=p_1\cdot p_2=0.8\cdot 0.9=0.72$

that is exactly 72%

9 1/2 divided by 3 7/10

OleMash [197]

Solution:

<u>Convert the fractions into improper fractions and solve.</u>

9 1/2 ÷ 3 7/10
=> 19/2 ÷ 37/10
=> 19/2 x 10/37
=> 19 x 5/37
=> 95/37

<u>Convert the fraction into mixed fraction (Not required):</u>

=> 95/37 = 37/37 + 37/37 + 21/37
=> 1 + 1 + 21/37
=> 2 + 21/37
=> 2 21/37

The solution to the problem is 2 21/37.
