Answer:

P(A n B) = 5

Step-by-step explanation:

From the venn diagram given, we can see that;

P(A) = 25

P(B) = 15

P(A n B) = 5

Thus,the correct answer of P(A n B) which is the intersection between A and B is 5

Just saying, this angle is a 45 degree angle.

and the X on both is '-1'

I think?

hope this helps. im not good at math..- :)

Tony flips a coin and gets heads. He tells his friend that he can get heads two more times in a row .what is the probability tha

Sergio [31]

Answer:

The probability is 1/8 or 0.125

Step-by-step explanation:

In this question, we are concerned with calculating the probability that when a coin is flipped there would be a show of heads three times.

In flipping of a coin, there are only two possible results with equal probability. The probability of both events i.e P(H) and P(T) is equal and that is 1/2

Thus the probability of getting heads three times in a row will be P(HHH) meaning P(H) and another P(H) and another P(H)

When we have and in a probability question, that means we are to multiply the probabilities together.

Hence, P(HHH) = 1/2 * 1/2 * 1/2 = 1/8

Solve the system using combination method to get a solution (x,y)<br> 4x+7y=10<br> -4x-6y=28

PIT_PIT [208]

$\left \{ {{4x+7y=10} \atop {-4x-6y=28}} \right. \\\\add\ those\ two\ equations\\\\
y=38\\\\
4x+7y=10\ \ \ | subtract\ 7y\\\\
4x=10-7x\ \ \ \ | divide\ by\ 4\\\\
x=\frac{10-7x}{4}=\frac{10-7*38}{4}=\frac{10-266}{4}=\frac{-256}{4}=-64\\\\
solution:\\ \left \{ {{y=38} \atop {x=-64}} \right.$
