Question

suppose a birth control pill is 97% effective in preventing pregnancy. (round your answers to three decimal places.) (a) what is the probability that none of 200 women using the pill will become pregnant?

Answer 1

The probability that none of 200 women using the pill will become pregnant is found to be 0.002.

How is probability calculated?

• The probability is computed by dividing the total number of possible outcomes by the number of possible ways the event might occur.
• Probability and odds are two distinct ideas.
• Odds are calculated by dividing the likelihood of an event by the likelihood that it won't.

Given: Assume a birth control pill has a 97% success rate in avoiding pregnancies.

Probability that none of 200 women using the pill will become pregnant is given as

= 0.97(200)

=0.0023

=0.002

Therefore, probability that none of 200 women using the pill will become pregnant is found to be 0.002.
