Solution:
First, it is important to determine the events
B1 : the card is red ace
B2 : The card is 10 or jack
B3 : the card is greater than 3 but it is less than 7
Then,
P(B1) = 2/52
P(B2/A1) = 8/51
P (B3/ B1 ∩ B2) = 12/50
To get the probability of
P (B1 ∩ B2 ∩ B3) = P (B1)P(B2/B1) P(B3/(B1 ∩ B2)
= (2/52)(8/51)(12/50)
= 8/5525
