What is the probability of flipping a coin 15 times and getting tails 10 times?

1 answer:

5 0

This is found using the binomial distribution with P(H) = 1/2 and P(T) = 1/2 n = 15 and r = 10

= nCr(0.5)^(15-10)(0.5)^10

= 15C10 * 0.5^15 = 0.0916 or 9.16%

Time sensitive question. Find the sum of the first 26 terms of an arithmetic series whose first term is 7 and 26th term is 93.

lisabon 2012 [21]

ANSWER

$S_{26}=1300$

EXPLANATION

The sum of an arithmetic sequence whose first term and last terms are known is calculated using

$S_{n}= \frac{n}{2} (a + l)$

From the given information, the first term of the series is

$a = 7$

and the last term of the series is

$l = 93$

The sum of the first 26 terms is

$S_{26}= \frac{26}{2} (7 + 93)$

$S_{26}= 13 (100)$

$S_{26}=1300$
