Question 1160784: Researchers at Namibia University of Science and Technology (NUST) have determined that
children under 2 years old who sleep with the light on have a 36 % chance of becoming myopic
before they are 16. Children who sleep in darkness have a 21 % chance of becoming myopic. A
survey indicated that 28% of children under 2 sleeps with some light on. Find the probability
that child under 16 is myopic.
You can put this solution on YOUR website! It is the expected value which is the sum of the two x*p(x)
0.28*0.36=0.1008
0.72*0.21=0.1512
the sum is 0.2520, the probability
