Barbara draws pens randomly from a box containing 5 pens of the same shape and size. There is 1 green pen, 3 red pens, and 1 blue pen. She draws 1 red pen and then another red pen without replacing the first one. Find the probability of drawing 1 red pen followed by another red pen, and show the equation used.

    0.3 cause 100/60=0.6 and 100/50 = 0.5 wich is 0.3 move dicemal point and u get 30%

    2/4= 50% is the Probability= Favorable Cases/Possible Cases

    The probability is 30%. I started of by using the fraction 3/5 which is 6% and then 2/4 which is 50%. Then i multiplied 3/5 and 2/4 which was .3 and then i changed it to a percentage which is 30%

    Looks good, but you might want to add why we used the fractions 2/4 and 3/5. Add that it is Probability= Favorable Cases/Possible Cases
