Together Kate and Matt have 47 cards. If Kate and Zach combine cards they have 126. If Matt and Zach combine they have 93. How m

Ede4ka [16]

Answer:

Matt has 7 cards.

Step-by-step explanation:

Let K, M and Z represent number of cards that Kate, Matt and Zach have.

We have been given that together Kate and Matt have 47 cards. We can represent his information in an equation as:

$K+M=47...(1)$

We are also told that Kate and Zach combine cards they have 126. We can represent his information in an equation as:

$K+Z=126...(2)$

Further, Matt and Zach combine they have 93. We can represent his information in an equation as:

$M+Z=93...(3)$

Upon subtracting equation (3) from equation (2), we will get:

$K-M=126-93$

$K-M=33$

$K=33+M$

Upon substituting this value in equation (1), we will get:

$33+M+M=47$

$33-33+2M=47-33$

$2M=14$

$M=\frac{14}{2}=7$

Therefore, Matt has 7 cards.

Find the probability that when a fair coin is flipped four times at least 2 heads

salantis [7]

Since the problem states "at least" we need to also find probability of 3 H or 4 H or 5 H

Now find the probability of flipping a head 4 times; $\frac{1}{2}$ ⁴
= (1/16)

Now probability of flipping a head 3 times: (4C3)(1/2)⁴ = 4/16

Probability of flipping a head 2 times; (4C2)(1/2)⁴=6/16

(1/16)+(4/16)+(6/16)=11/16

Probability of flipping a fair coin 4 times with at least 2 heads is 11/16.

Hope I helped :)
