Help me please ASAP

Mashutka [201]

Answer: $\frac{5}{35}$

Step-by-step explanation:

Since, the total number of contestant = 7,

Thus, the probability that out of 3 contestant, me and my friend is chosen

= $\frac{2_C_2\times 5_C_1}{7_C_3}$

= $\frac{\frac{2!}{2!0!}\times \frac{5!}{1!\times 4!}}{\frac{7!}{4!\times 3!}}$

= $\frac{1\times 5}{\frac{7\times 6\times 5\times 4!}{4!\times 6}}$

= $\frac{5}{35}$

⇒ Third Option is correct.

Chris has 18 marbles and Kevin has 15 marbles. Chris gave half of his marbles to Kevin.

Helen [10]

Ok so…
The answer is: 15 more marbles
Because
18 divided by 2 is 9
15+9=24
Now Chris has 9
Kevin has 24
24-9=15
Hope this helps:)
