Answer:

1−0.03125=0.96875

Step-by-step explanation:

The probability of having a male or female child is equal (0.5).

So having your first child means you have a 50% chance of a male. Your second child being male also will have a probability of

0.5x0.5=0.25 .

The only scenario in which a couple with five children do not have at least one son is if all five children are female.

So the pribability of having five females is  0.55=0.03125  

So if every other scenario means the couple have at least one son, and the total probability of an event is 1, we can find the probability of having at least one son with

1−0.03125=0.96875

702 can not be written as the product of 2 prime numbers, because if you divide 702 by 2 then you get 351 and that is not a prime number. Therefore 702 is a prime number.

1) Experimental probability of drawing a Club = 9 / 40

The experimental probability is the probability of the event occurring in the experiment. You use your results to find the experimental probability. This is over the total amount of trials. In this experiment, 9 clubs were drawn. Thus, the experimental probability of drawing a club is 9 / 40.

2) Relative frequency of drawing a Spade = 1 / 5

Relative frequency is the same as experimental probability. You use your results and set the experiment number over the total number of trials. Thus, the relative frequency of drawing a Spade is 8 / 40, or 1 / 5.

3) Theoretical probability of drawing a Heart = 1 / 4

The theoretical probability is the expected probability. There are 13 hearts out of a full deck of 52 cards. Thus, the theoretical probability of drawing a heart is 13 / 52 or 1 / 4.

4) Theoretical probability of drawing a Club or Diamond = 1 / 2

The theoretical probability is the probability that is expected. In this scenario, it will be the number of clubs plus the number of diamonds in a deck of cards over the total number of cards in a full deck. And, or means that either probability could occur and we should add. Thus, the theoretical probability of drawing a club or diamond is 26 / 52 or 1 / 2.

5) The difference between experimental and theoretical probability is that experimental probability is the probability of an event occurring based on your experiment and results. The theoretical probability is the expected probability of an event occurring. It is not based on your experiment, and in a completely fair experiment, would be the probability of an event occurring. For example, flipping a coin. The theoretical probability of getting heads when you flip a coin is 0.5. But say in your experiment of 50 trials you get heads 15 times. The experimental probability would be 15 / 50.

Hope this helps!! :)

How to solve (x-10)(x + 10)
alexandr402 [8]

Answer:

x² - 100

Step-by-step explanation:

Use the FOIL method. The FOIL method is the way in which you multiply the terms:

FOIL stands for First, Outside, Inside, Last. Multiply:

First:

x * x = x²

Outside:

x * 10 = 10x

Inside:

-10 * x = -10x

Last:

-10 * 10 = -100

Combine like terms:

x² + 10x - 10x - 100

x² + (10x - 10x) - 100

x² - 100

x² - 100 is your answer.

Find the value of y such that the distance between the given points is indicated..... (5,y) and (8,-1) is 5.
maw [93]
(5,y)(8,-1)
d = sqrt ((x2 - x1)^2 + (y2 - y1)^2)
d = sqrt ((8 - 5)^2 + (-1 - y)^2)
d = sqrt (3^2 + (-1 - 3)^2
d = sqrt (9 + (-4^2)
d = sqrt (9 + 16)
d = sqrt 25
d = 5

so ur points are : (5,-3)(8,-1)
