Answer:

\frac{5}{26}

Step-by-step explanation:

We need to find the probability of rolling an even number on a die and the probability of drawing an even number in the deck, and then multiply both.

There are the numbers 2, 4, and 6 on a die, and there are 6 numbers in total, so the probability of rolling an even number is 3/6 or 1/2.

The even numbers in a deck are 2, 4, 6, 8, and 10, so 5 in total. We multiply 5 by 4 because there are 4 of every card and we get 20 even number cards. The probability is 20/52 or 5/13.

\frac{1}{2} x \frac{5}{13} is \frac{5}{26}.

Answer:

1/4

Step-by-step explanation:

There are 54 cards in a deck including jokers, so if you count how many face cards there are and jokers and subtract them from 54 you get 40, then you divide 40 by 2 to get 20/40 since it is even numbered and half of the time you would get an even number. then you divide the die by 2 to get 1/2 and multiply them to get your answer 1/4.

Oops some miscalculations.

More miscalculations.

probability that Marnie and Noomi are both selected=0.1

Step-by-step explanation:

A group of 5 managers (Joon, Kendra, Lee, Marnie and Noomi), 2 people are randomly selected to attend a conference in Las Vegas.

the possibility of selecting 2 from 5 manages is 5C2 ways

5C2= \frac{5!}{2!(5-2)!} =10

There is only one choice of selecting Marine and Noomi from 5 managers

So probability of selecting Marine and Noomi is

\frac{1}{10} =0.1
