Answer with Step-by-step explanation:

Since the given event is binary we can use Bernoulli's probability to sove the problem

Thus for an event 'E' with probability of success 'p' the probability that the event occurs 'r' times in 'n' trails is given by

P(E)=\frac{n!}{(n-r)!\cdot r!}\cdot p^{r}\cdot (1-p)^{n-r}

Part a)

For part a n = 11 , r =9, p = 0.75

Applying values we get

P(E)=\frac{11!}{(11-9)!\cdot 9!}\cdot (0.75)^{9}\cdot (1-0.75)^{11-9}\\\\\therefore P(E)=0.2581

Part b)

For part b n = 20 , r = 16 , p=0.75

Applying values we get

P(E)=\frac{20!}{(20-16)!\cdot 16!}\cdot (0.75)^{16}\cdot (1-0.75)^{20-16}\\\\\therefore P(E)=0.1896

WILL MARK THE BRAINLEST!
eduard
Okay so the relationship between points K and K' is that you subtract 4 from the x values and you add 6 to the y values.

1 - 4 = - 3

L ( - 3 , 3 ) ==> L' ( - 3 - 4 , 3 + 6 ) ==> L' ( - 7 , 9 )

The only answer option with L' as such is answer choice B.

I hope that helps you out!!

Let p: A number is greater than 25.
maria [59]
We are given that:
p is greater than 25, this means that p>25
p ∈ ]25,∞[ ...........> interval I

q is less than 35, this means that q<35
q ∈ ]-∞,35[ ...........> interval II

The given condition <span>p ∧ q is true means that (p and q) is true. In other word, their intersection is true.
Therefore, the final result would be the intersection between the two intervals (interval I and interval II)

Bases on the above, the final answer would be:
</span>]-∞,35[  ∧ ]25,∞[  which is ]25,35[<span>

</span>

(2 5/8 + 5/6) + 1 1/8 in simplest form?
Leona [35]

Result:

5 /5  : 1 /2  = 5 /5 · 2 /1   = 5 · 2 /5 · 1   = 10 /5  = 2

To divide one fraction by another, invert (turn upside-down) the second fraction, then multiply.
