The probability of choosing a penny from the 1980s from the bag of pennies without looking is 3/40 . which term best describes this probability?

Unlikely

Step-by-step explanation:

Given: The probability of choosing a penny from the 1980s from the bag of pennies without looking=

We know that the probability of any event lies between 0 and 1.

Since, 0.075 lieas between 0 and 0.5, therefore the event is said to be unlikely.

solution:

→c= a b , that is product of a and b is possible only when when a is m × n matrix and b is n × p matrix.

that is, number of columns of a= number of rows of b.

so, size of matrix , c= a b is , if a = (m × n)matrix

b= (n × p)matrix

then a b = [ (m × n)matrix] ×[   (n × p)matrix ]

→→c= a b= [m × p ] matrix

→→size of product a b will be equal to = number of rows of a × number of columns of b

(a) the volume of the cone is 20/3 in3

hence, option a is correct.
