Answer: The probability is 1/2
Step-by-step explanation:
A die has 6 sides, 3 of which are prime numbers. These are 2, 3 and 5.
There are 4 dice so there are 24 faces.
Only 3 numbers on the dice are prime.
So 3 prime numbers on 4 dice would be 12 numbers.
12 prime numbers/24 total numbers
=1/2
Inverse variation:
y - the intensity of illumination, x - the distance from the light source
When the distance is 8 inches, the intensity is 12 lm.
When the distance is x inches, the intensity is 3 lm.
The distance can't be a negative number, so x=16.
The photoelectric cell is 16 inches from the light source.

(12x2) +22+20+18+72+14+12+0+8+6+4+2= 202
