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
Answer:83 and 97
Step-by-step explanation:
Let the angle be y
The second angle will be y+14
A supplementary angle equals 180°
y + y + 14=180
2y+14=180
2y=180-14
2y=166
y=166/2
y=83
The first angle is 83.
Second angle will be 83+14=97.
