At a local elementary school, 35 percent of all students have brown eyes, 45 percent have brown hair, and 60 percent have brown

sveta [45]

Answer:

No they are not mutually exclusive

Explanation:

We have given that 35 % of the students have brown eyes

So $n(A)=35$ %

And 45 % of the student has brown hair

So $n(B)=45$ %

It is also given that 60 % of the student have both brown eyes and brown hair

So $n(A\cup B)=60$ %

From set rule we know that

$n(A\cup B)=n(A)+n(B)-n(A\cap B)$

So $60=45+35-n(A\cap B)$

$n(A\cap B)=20$

So A and B will not be mutually exclusive because for A and B to be mutually exclusive $n(A\cap B)$ must be zero

Alisiya [41]

Answer:

Explanation:

A turtle naturally withdraws in its head and limbs when its shell is tapped. You want to teach your turtle, by classical conditioning, to withdraw its head and limbs when you say "Boo." Consequently, you say "Boo" and then tap its shell on numerous occasions. Eventually your turtle withdraws its head and limbs when you say "Boo" alone. In this example, the Conditioned Response (CR) is to withdraw its head and limbs when you say "Boo."

A conditioned response is a behavior that does not come naturally, but must be learned by the individual by pairing a neutral stimulus with a stimulus.

In this case the neutral stimulus will be saying the word Boo the other stimulus is tapping its shell to produce withdrawing its head and limbs
