Answer:
1. 50%
Step-by-step explanation:
For each day, there are only two possible outcomes. Either it does rain, or it does not, so we use the binomial probability distribution to solve this problem.
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.
In which 
is the number of different combinatios of x objects from a set of n elements, given by the following formula.
And p is the probability of X happening.
In this problem we have that:
We want to find
NNN + RNN + NRN + NNR
This is
So
![P(X = 1) = C_{3,1}.(0.5)^{1}.(0.5)^{2} = 0.375/tex][tex]P(X \leq 1) = P(X = 0) + P(X = 1) = 0.125 + 0.375 = 0.5](https://tex.z-dn.net/?f=P%28X%20%3D%201%29%20%3D%20C_%7B3%2C1%7D.%280.5%29%5E%7B1%7D.%280.5%29%5E%7B2%7D%20%3D%200.375%2Ftex%5D%3C%2Fp%3E%3Cp%3E%5Btex%5DP%28X%20%5Cleq%201%29%20%3D%20P%28X%20%3D%200%29%20%2B%20P%28X%20%3D%201%29%20%3D%200.125%20%2B%200.375%20%3D%200.5)
The correct answer is:
1. 50%
Answer:
Step-by-step explanation:
y/3-5=3
add 5 to both sides
y/3=8
multiply both sides by 3
y=8 x 3
y=24
Assuming that you're talking about a standard deck of 52 cards, there are 4 tens and 4 aces.
So, at the beginning, you have probability 4/52=1/13 to draw a ten.
You replace, and you have an identical probability to draw an ace (you still have 4 favourable cases over 52 total cases).
Multiply the two probabilities to find the answer:
If i’m not mistaking i believe the answer is linear combination
The answer is:
20 <span>≥ 6+2c.
He wants to sell at least 20 items, and he already sold six.
since each person buys 2, we multiply that by 'c', the number of customers.</span>
