dance. Using this information, answer each of the following questions.
Let Y be the event that a randomly selected gym member regularly attends yoga and D be the event that a
randomly selected gym member regularly attends dance.
What is P(Y), the probability that a gym member attends yoga?
What is P(D), the probability that a gym member attends dance?
What is P(Y and D), the probability that a gym member attends yoga and dance?
What is P(Y or D), the probability that a gym member attends yoga or dance?

the total estimated nappy use.=10,500,000

step-by-step explanation:

given that on an average the average baby uses 3528 napkins.

in a particular year 2014, the number of births were 299697 in new south wales.

rounding off the number of births to the nearest hundred thousand we have

no of birtsh = 300000

also rounding off the average usage to nearst thousand we get

average use of a baby = 3500

hence total number of nappy estimated to be used = 3500x300000

= 10,500,000

answer is 10,500,000 nappies

they charge the same amount at 20 minutes.

step-by-step explanation:

the circumference of a circle is, 10.676 cm.

step-by-step explanation:

the formula for circumference of a circle is given by:

where

c is the circumference of a circle and

d is the diameter of a circle.

given: diameter(d) = 3.4 cm and use

substitute these values in [1] we get;

cm

therefore, the circumference of a circle is, 10.676 cm
