Answer:

A. the number of possible out comes

Step-by-step explanation:

Probability is the chance of an event/something to happen.

The formula is;

Probability = the number of ways of achieving success/Total number of outcomes

The numerator position will have a value to show the number of ways of achieving success while the denominator will show the number of outcomes

For example the number of possible outcomes when a coin is flipped is 2, a tail or a head. So the probability of getting a head is P(H)= 1/2 where 2 is the number of outcomes

In a recent year 21.6% of all registered doctors were female if there were 54,100 female registered doctors that year what was t
oksian1 [2.3K]

Answer:the total number of registered doctors is 250463

Step-by-step explanation:

Let x represent the total number of registered doctors

In a recent year 21.6% of all registered doctors were female. It means that the number of registered female doctors would be

21.6 /100 × x = 0.216 × x = 0.216x

if there were 54,100 female registered doctors that year, it means that

0.216x = 54100

x = 54100/0.216 = 250463

A 40-degree angle is translated 5 inches along a vector. What is the angle measurement, in degrees, of the Image?
vagabundo [1.1K]

Answer:

40°

Step-by-step explanation:

As clarified in an online document, a translation along a vector (which is a line in a plane) of a figure, is equivalent to a translation along a coordinate grid, and therefore, given that a translation is a form of rigid transformation, the the dimensions and inclinations of the rays forming the preimage are the same as those in the image and the angles measurement in the preimage and the image are equal.

Therefore, given that the angle measurement of the image is 40-degrees, the angle measurement of the image is also 40-degree (40°) angle.

After flying between two black holes, our engines have been a bit janky. The probability of one of any of our 8 power couplings
otez555 [7]

Answer:

Step-by-step explanation:

We would apply the formula for binomial distribution. It is expressed as

P(x = r) = nCr × q^(n - r) × p^r

Where

p represents probability of success

q represents probability of failure.

n represents number of sample.

From the information given,

p = 10% = 10/100 = 0.1

q = 1 - q = 1 - 0.1 = 0.9

n = 8

1)The probability that none fails is

P(x = 0) = 8C0 × 0.9^(8 - 0) × 0.1^0

P(x = 0) = 0.43

2) The probability that one fails is

P(x = 1) = 8C1 × 0.9^(8 - 1) × 0.1^1

P(x = 1) = 0.38

3) The probability that four fails is

P(x = 4) = 8C4 × 0.9^(8 - 4) × 0.1^4

P(x = 4) = 0.0046

3) The probability that six fails is

P(x = 6) = 8C6 × 0.9^(8 - 6) × 0.1^6

P(x = 6) = 0.00002268

4) The probability that eight fails is

P(x = 8) = 8C8 × 0.1^(8 - 8) × 0.1^8

P(x = 8) = 0.00000001
