Answer:
x=
Step-by-step explanation:
For coin there are two possible outcomes: head or tail.
For 3-color spinner you have three possible outcomes: red, blue and yellow.
Tossing a coin once and then spinning a 3-color spinner once you'll have 6 posiible outcomes:
- head + red;
- head + blue;
- head + yellow;
- tail + red;
- tail + blue;
- tail + yellow.
Im guessing the question is incomplete or not supposed to be in math section but a logical answer would be: Its the King ;-;
Answer:
n^2 +14n +49
Step-by-step explanation:
(n+7)^2
(n+7) (n+7)
FOIL
first = n*n
outer = n*7
inner = 7*n
last 7*7 =49
Add them together
n^2 +7n+7n+49
Combine like terms
n^2 +14n +49
Answer:
Step-by-step explanation:
We would apply the formula for binomial distribution which is expressed as
P(x = r) = nCr × p^r × q^(n - r)
Where
x represent the number of successes.
p represents the probability of success.
q = (1 - r) represents the probability of failure.
n represents the number of trials or sample.
From the information given,
p = 18% = 18/100 = 0.18
q = 1 - p = 1 - 0.18
q = 0.82
n = 5
Therefore,
P(x ≤ 2) = p(x = 0) + p(x = 1) + p(x = 2)
P(x = 0) = 5C0 × 0.18^0 × 0.82^(5 - 0)
P(x = 0) = 0.37
P(x = 1) = 5C1 × 0.18^1 × 0.82^(5 - 1)
P(x = 1) = 0.41
P(x = 2) = 5C2 × 0.18^2 × 0.82^(5 - 2)
P(x = 2) = 0.18
Therefore,
P(x ≤ 2) = 0.37 + 0.41 + 0.18 = 0.96
