Answer:
P = 10/171
P = 0.058
The probability that both fish selected are Catfish is 0.0058
Step-by-step explanation:
Given:
The tank contains;
Algae eaters = 8
Catfish = 5
Tilapia fish = 6
Total number of fish = 8+5+6= 19
To determine the probability that both fish selected are Catfish P;
P = 5/19 × 4/18
( The number of the total number of fishes, and Catfish reduce by one after each selection because it is selected without replacement)
P = 10/171
P = 0.058
x= r - h/y subtract r from both sides
x-r = -h/y multiply each side by -y
-y(x-r) = h
-xy +yr = h
Answer:
the answer is 2 4/5
Step-by-step explanation:
there are two wholes plus 4 out of 5 pieces, so it is 2 and 4/5.
