There are 91 in total. Since there are 21 red cars, it would give you 21/91. Around a 23.07% chance.
Answer:
a) 0.1091
b) 0.9994
c) 0.5886
Step-by-step explanation:
X = the number of fish out of 20 that die after 24 hours
x = 0, 1, 2, . . . , 20
X~ Binomial (n= 20, p =0.20)
P(14 survive) = P(X = 6)
=
=0.1091
Similarly we can find out
P(at least 10 survive) = P( X <= 10 ) = (Using technology) = 0.9994
P(at most 16 will survive) = P(X <= 16) = (Using technology) = 0.5886
4x + 1 → C
(f + g)(x) = f(x) + g(x) = 3x - 1 + x + 2 = 4x + 1
Regroup: (4x³-12x²)+(7x-21)
factor: 4x²(x-3)+7(x-3)
factor again: (x-3)(4x²+7)
Answer:
C

You start with 3 and subtract a number
