If you decide to play a Pick 3 lottery game, in which you have to guess the exact order of the three numbers, what is your probability of winning? All 3 numbers will be between 0 and 9 and can be chosen more than once. A. 1/100 B. 1/1000 C. 3/1000 D. 1/720

Answers

Answer 1
Answer:

Answer:

Option B is correct.

Step-by-step explanation:

We have been given that  3 lottery games have decided to play

So, here we have total possibility of numbers s between 0 and 9 which is total of 10 numbers

And number can be chosen more than once.

So, the probability will be (1)/(10)\cdot (1)/(10)\cdot (1)/(10)

On simplification we will get

the probability of winning (1)/(1000)

Therefore, option B is correct.

What is a 2 digit number, less than 50 that can be divided by 4 exactly and when 4 is added to it it can be divided by 5 exactly

Answers

ok

divisible by 4 exactly measn that it is even
ends with 0,2,4,6,8

when you add 4 it divides by 5, if it is divisble by 5 it ends with 0 or 5
the possible numbers under 50 that are divisble by 5 are
5,10,15,20,25,30,35,40,45

if you add 4 to the mystery number, you get divisible by 5
minus 4 from all of that list and see which s divisible by 4
1,6,11,16,21,26,31,36,41

Answers

Y=x^3+4 because if you mulitiply x 3 times and then add it by 4 then you should get y
y = x³ + 4 will be our equation

Because:

5=1³ + 4
5 = 1 +4
5 = 5       (its correct)

129 = 5³ + 4
129 = 125 + 4
129 = 129
