Answer:

P U Q = {2, 3, 4, 5, 6, 7, 8, 9, 10}

P ∩ Q = {4, 6, 8}

Step-by-step explanation:

P = {2x, for 1 <= x <= 5}

P = {2, 4, 6, 8, 10}

Q = {x + 1, for 2 <= x <= 8}

Q = {3, 4, 5, 6, 7, 8, 9}

P U Q = {2, 3, 4, 5, 6, 7, 8, 9, 10}

P ∩ Q = {4, 6, 8}

Can someone please anwser

Since all three equations are equal, you take 15 x 20, which =300, once again because all of the equations are equal, take 300 and divide it by 5, that will give you your first question mark.{you should have gotten 60.} To find the second one, you are going to apply the same concept, Take 300 and divide it by 6, giving you your second question mark. {you should have gotten 50}...
P.S.: {hope I helped} :)

Consider a roulette wheel consisting of 38 numbers 1 through 36, 0, and double 0. If Smith always bets that the outcome will be

zimovet [89]

Answer:

0.003

Step-by-step explanation:

Given: A roulette wheel consists of 38 numbers 1 to 36, 0, and double 0.

Smith bets that the outcome will be one of the numbers 1 through 12.

To find: probability that Smith will lose his first 5 bets

Solution:

Probability refers to chances of occurrence of some event.

Probability = Number of favourable outcomes/Total number of outcomes

Total number outcomes = 38

As Smith bets that the outcome will be one of the numbers 1 through 12, number of favourable outcomes is equal to 12.

So,

probability that Smith will loss his first bet = $\frac{12}{38}=\frac{6}{19}$

Therefore,

Probability that Smith will lose his first 5 bets = $(\frac{6}{19} )^5=0.003$
