Answer:

Probability = 0.894

Expected value = 5.2

Standard deviation = 1.349

Step-by-step explanation:

Given that

p = 0.65

n = 8

q = 1 - p

= 1 - 0.65

= 0.35

P(x) = ^n(c_x)\times P^x\times q^{n-x}

For P(3)

= ^8c_3\times 0.65^3\times 0.35^5

Which gives result

= 0.0808

For P(2)

= ^8c_2\times 0.65^2\times 0.35^6

Which gives result

= 0.0217

For P(1)

= ^8c_1\times 0.65^1\times 0.35^7

which gives result

= 0.0033

For P(0)

= 0.35^8

= 0.0002

Now probability is at least getting admitted of 4 students

= 1 - {P(3) + P(2) + P(1) + P(0)}

= 1 - (0.0808 + 0.0217 + + 0.0033 + 0.0002)

= 1 - 0.106

= 0.894

Expected value = n\times p

= 8\times 0.65

= 5.2

Standard deviation

= \sqrt{n\times p\times q} \\\\\ = \sqrt{8\times 0.65\times 0.35}

= 1.349
