Step-by-step explanation:
Answer:
0.991
Step-by-step explanation:
Let Q be probability none of the 4 are vaccinated.
Let P be probability that at least 1 is vaccinated.
P = 1 - Q
Now if 69% are vaccinated, then 31% are not vaccinated.
Thus any given person has a probability of 0.31 of not being vaccinated.
Q = (0.31)^4 = 0.00924
P = 1 - 0.00924 = 0.991
Answer:
Explanation:
1.
(x + 6)(x + 4)
= x^2 + 4x + 6x + 24
= x^2 + 10x + 24
2.
(y - 9)(y+2)
= y^2 + 2y - 9y - 18
= y^2 - 7y - 18
3.
(m + 7)(m - 5)
= m^2 - 5m + 7m - 35
= m^2 + 2m - 35
4.
(2x + 3)(4x + 1)
= 8x^2 + 2x + 12x + 3
= 8x^2 + 14x + 3
5.
(4y - 5)(y + 4)
= 4y^2 + 16y - 5y - 20
= 4y^2 + 11y - 20
