HELP A Box Has One Red Marble One Blue Marvel And Four Green Marbles Of The Same Shape And Size Dan Draws A Marble Randomly From The Box Places It And Then Draw class=

Sagot :

Answer: 1/16

Step-by-step explanation:

Given that there are 4 green marbles, when Dan takes a marble the first time, the probability is 1/4 as there are 4 green marbles. When he puts it back and draws another one, the probability is still 1/4 because Dan didn't take the marble out of the bag(this is known as with replacement)

∴ the total probability of drawing 2 green marbles with replacement is 1/4 × 1/4= 1/16

Hope this helps
