The probability that an event occurs is the number of times it could occur compared to the total number of possible events, assuming the probability of each event occurring is equal.

John has $4+8=12$ coins total. If 4 of the coins are dimes, the probability that he draws a dime is $\frac{4}{12}=\frac{1}{3}\approx 33\% \approx 0.33$ .

Of five letters (A, B, C, D, and E), two letters are to be selected at random. How many possible selections are there?

taurus [48]

Answer: d. 10

Step-by-step explanation:

We know that the number of combinations of r objects selected from a group of n objects at a time is given by :-

$^nC_r=\dfrac{n!}{(n-r)!r!}$

Given : The total number of letters = 5

The number of letters need to select = 2

Then , the number of combinations of 2 letters selected from a group of 5 letters at a time is given by :-

$^5C_2=\dfrac{5!}{(5-2)!2!}=\dfrac{5\times4\times3!}{3!\times2}=10$

Hence, there are 10 possible selections.

Y-y1=m(x-x1)
m= slope =-3
y-y1=-3(x-x1),
y1=-7, x1=5
y--7=-3(x-5)
y+7=-3(x-5) this is C
