Mr. Hon purchases a new car every 4 years. Ms. Jasper purchases a new car every 6 years. They both purchased new cars this year.

Kipish [7]

Answer:

12 years

Step-by-step explanation:

Given that Mr. Hon purchases a new car every 4 years. Ms. Jasper purchases a new car every 6 years.

Assuming that they purchase new cars together after n years.

So, n must a multiple of 4 as well as multiple 6, i.e the number n is the lowest multiple (LCM) of 4 and 6.

As LCM od 4 and 6 is 12, so n=12.

Hence, after 12 years they will purchase news cars together.

What is the probability of getting two heads in an experiment of tossing two coins at the same time? h 1/4 С a 50% 0 I don't kno

Svet_ta [14]

The probability of tossing a coin of getting head is 1/2 because there are two faces in the coin one of them is head

P(h) = 1/2

Since there are two coins will tossing together, then the probability of each coin getting a head is 1/2

We need to getting head in both, then we will multiply the two of them

$P(h\text{ and h) =}\frac{1}{2}\times\frac{1}{2}=\frac{1}{4}$

Then the probability is 1/4
