Nostrana [21]

Answer:

B. Events A and B are mutually exclusive if A and B have no sample points in common.

Step-by-step explanation:

When two events( call them A and B) are mutually exclusive , it is impossible for them to happen together.

P(A and B) = 0

"The probability of A and B together equals 0 (impossible)"

Hence, the correct answer is B.

At the school carnival, students are asked to guess the number of marbles in a jar to win a prize. There are 240 marbles in the
Lapatulllka [165]

There is 17% error in the guess.

Step-by-step explanation:

Given,

Number of marbles in jar = Exact value = 240

Closest guess = Approx Value = 280

Percent error = \frac{|approx-exact}{exact}*100

Percent error = \frac{|280-240|}{240}*100\\

Percent error = \frac{|40|}{240}*100

Percent error = \frac{4000}{240}=16.67\%

Rounding off to nearest whole percent

Percent error = 17%

There is 17% error in the guess.
