1 1/2 * 1/3
= 3/2 * 1/3
= 3/6
= 1/2.
So John used 2*1/2 = 1 meter of the ribbon.

Answer:
I have to say it's either D or A. I'm not really good with math though, good luck!
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
