P(orange and then a purple) is 15/56.
P(two purples in a row) is 6/56.
<u>Step-by-step explanation:</u>
- A bag contains 3 purple and 5 orange jelly-beans.
- The total jelly-beans in the bag = 3 purple + 5 orange = 8 jelly-beans.
<u>Without replacement, find P(orange and then a purple) :</u>
P (orange) = No.of orange jelly-beans / total jelly-beans.
⇒ 5 / 8
P (purple) = No.of purple jelly-beans / remaining jelly-beans from the total
⇒ 3 / 7
P(orange and then a purple) = P (orange) × P (purple)
⇒ 5/8 × 3/7
⇒ 15/56
<u>Without replacement, find P(two purples in a row) :</u>
P (1st purple) = No.of purple jelly-beans / total jelly-beans.
⇒ 3 / 8
P (2nd purple) = remaining no.of purple jelly-beans / remaining jelly-beans from the total.
⇒ 2 / 7
P(two purples in a row) = P (1st purple) × P (2nd purple)
⇒ 3/8 × 2/7
⇒ 6/56
