Can some one help me asap

zavuch27 [327]

It'd be easier to do #18 if y ou were to break it up:

14* (first term + 14th term)
Sum from n=1 to 14 of n = S = ---------------------------------
14 2

14(1+14)
= ---------------- = 7(15) = 105
2

The sum of twice that is 210. The sum of "1 from n=1 to n=14" is just 14.

The final sum is 210 + 14 = 224 (answer)

Find the probability for choosing a letter at random from the word: Probability P(not P) A.) 1/11 B.) 2/11 C.) 5/11 D.) 10/11

elixir [45]

Answer:

D.) 10/11

Step-by-step explanation:

Here the given word Probability has 11 letters in it. And we have to calculate the Probability of not selecting a letter P from the above word.

So the formula for calculating any probability is Total Favorable outcomes / Total number of outcomes.

Here total number of outcomes are 11 as word Probability has 11 letters.

So the probability of selecting letter P from word Probability = $\frac{1}{11}$

Now the P(not P) = 1 - P(selecting letter P)

= 1 - $\frac{1}{11}$ = $\frac{10}{11}$
