The total number of marbles in the urn = 25 marbles
Number of red marbles in the urn = 15 marbles
The probability of picking the first one as red = Number of red marbles/ total number of marbles = 15/25 = 3/5
Now, for the second draw, number of marbles = 24 (Since you already picked one)
Total number of orange marbles = 8
The probability of picking the second one as orange = Number of orange marbles/ total number of marbles = 8/24 = 1/3
Probability of picking a red in the first draw and an orange in the next draw =3/5*1/3 = 1/5
Probability of picking a red in the first draw and an orange in the second draw = 1/5
