P(Large|red)    P(blue or large)

plainntall · Answer

Probability will be the number of specified marbles/total marbles right?

What is the total number of marbles?

What is the total of Large Red marbles?

What is the total of all large marbles plus small blue marbles?

From that information can you calculate the Probability of Large Red Marbles being picked and either a Large Marble or a small blue marble being picked?
