Use the normal distribution to approximate the following binomial distribution: A die is rolled 84 times. What is the probability that the number 2 occurs more than 11 times?

answer

a,b, and d

explanation

a reflection angle is more than

but less than;

an angle that measures

is a reflex angle.(true)

an angle that measures less than

is acute.(true)

provided we are considering angles greater or equal to zero.

an acute angle lies in the range.

an obtuse angle is less than 180° but more than 90°

an angle that measures 300° is obtuse (false)

an angle that measures 65° is an acute angle.(true)

b, i believe, but not sure.

false

inverse variation is not exponential
