128=2⁷
2^2a x 2^2a=2⁷
2^(2a+2a)=2⁷
2^4a=2⁷

Therefore:
4a=7
a=7/4
a=1.75

Answer: a=1.75

To check
2²⁽⁷/⁴⁾ * 2²⁽⁷/⁴⁾ =2⁷/² * 2⁷/²=2¹⁴/²=2⁷=128

A binomial experiment has the given number of trials N and the given success probability P.
yan [13]

The probability of the success will be 0.3826.

<h3>What is binomial distribution?</h3>

Bernoulli's trials are those trials which end up randomly either on success (with probability p) or on failures (with probability 1- p = q (say))

The probability that out of n trials, there'd be x successes is given by

\rm P(x) = \: ^nC_xp^x(1-p)^{n-x}

We have

n = 8

p = 0.1

q = 1 – 0.1 = 0.9

x = 1

Then we have

P(1) = ⁸C₁ x (0.1)¹ x (0.9)⁷

P(1) = 0.3826
