If 15 actuators have failed today, what is the probability that a) at least 10 are repairable? b) from 3 to 8 are repairable? c)
Ann [662]

The probabilities of at least 10 are repairable is 1/3. and probabilities of from 3 to 8 are repairable is 1/5*8/15 and probabilities of exactly 5 are repairable is 1/3.

According to the statement

we have given that If 15 actuators have failed and we have to find the probabilities on some conditions.

we know that the formula of probabilities is

probability = possible outcomes / total outcomes

So,

  • at least 10 are repairable = 1 - (10 are not repairable)

at least 10 are repairable = 1 - 10/15

at least 10 are repairable = (15 - 10)/15

at least 10 are repairable = (5)/15

at least 10 are repairable = 1/3

  • from 3 to 8 are repairable = 3/15 *8/15

from 3 to 8 are repairable = 1/5 *8/15

  • exactly 5 are repairable = 5/15

exactly 5 are repairable = 1/3

These are the probabilities of the given conditions.

So, The probabilities of at least 10 are repairable is 1/3. and probabilities of from 3 to 8 are repairable is 1/5*8/15 and probabilities of exactly 5 are repairable is 1/3.

HELP FAST PLEASE
Nimfa-mama [501]

Answer:

a. 0

Step-by-step explanation:

1.  To find the slope given two points, use the following formula:

\frac{y^{2}- y^{1} }{x^{2}-x^{1}  }

2. y^{2} would be the second y-value (in the second ordered pair), 2, and y^{1} would be the first y-value (in the first ordered pair), also 2.

3. Same for the x-values. x^{2} is -2 and x^{1} is 4

4. Now plug in the values.

\frac{2-2}{(-2)-4}

5. This equals \frac{0}{-6} which simplifies to 0
