Using the Binomial Probability table, find P(X) when n = 7, X < 3, and p = 0.5 A. 0.273 B. 0.500 C. 0.227 D. 0.773
Nat2105 [25]

Answer:

0.227

Step-by-step explanation:

Given that X is binomial with n=7 and p =0.5

To find the probability for P(X<3)

i.e. we have to find prob as =P(x=0,1,2)

=P(X=0)+P(X=1)+P(x=2)

P(X=r)=7Cr(0.5)^7

Using binomial table we find prob

P(X<3)=0.2265

Round off this to 3 decimals as

0.227

Hence answer is 0.227

Can you please help me I don't understand
MA_775_DIABLO [31]
For #11 you add 54 + 59+ 57+ 54. Then you have 224. Then divide 224 by 4 since there are 4 numbers. Your answer should be 56 inches as the average, or mean.
Remember, when you divide, you divide by the number of all the numbers. I'm trying to make sense but hope this helps!

QUICKLY PLEASE!!<br> 18POINTS!<br> 6(3p – 2) = 24
Gekata [30.6K]

Answer:

p= 2

Step-by-step explanation:

So first you want to distribute the 6 to 3p-2 which basically means multiply

6(3p – 2) = 24

6 times 3p is 18 and 6 time -2 is -12

* remember a negative and a positive equal a negative*

18p-12=24

you want to get 18p by itself, so in order to do that you can add 12 to both sides because if you add 12 on the left side it cancels out -12 and whatever you do to one side you have to do it to the other so add 12 to 24 which is 36

18p = 36

since you want to get p by itself you divide p on both sides so it can cancel out 18 and 36/18 is 2

so p = 2

if you are wondering why i divide it and not subtract or add it is because 18 and p are stuck together so you have to divide but if it  was like 18 + p you can subtract because 18 and p arent together
