It has been observed in one country, that 61 out of every 100 births is a baby with brown eyes. In 640 births how many brown eyed babies would you expect?
what is (61/100)(640) rounded to the nearest whole number ?
To determine how many brown-eyed babies you would expect out of 640 births, you can use the observed rate of brown-eyed births.
It is given that in this particular country, 61 out of every 100 births result in a baby with brown eyes. This can be expressed as a fraction: 61/100 = 0.61.
To find the expected number of brown-eyed babies out of 640 births, you multiply the fraction by the total number of births:
Expected number of brown-eyed babies = 0.61 * 640
Calculating this expression gives you the answer.
