Question: A box contains 60 marbles of which 21 are large(the rest are small) and 27 are red ( the rest are white). Exactly four of the large marbles are white. A marble is chosen at random from the box. Let L stand for the event a large marble is chosen, S for small, R for red, and W for white. Find the following probabilities. (hint: set up a 2x2 contingency table with color along one side and size along another. Include totals for the rows and columns.)

Contingence table:

a) P(L or R)

B) p(L)

C) P(s and w)

D) P(w or R)

E) P(L or W)

F) P(S complement)

G) P(L or S)

H) P(L complement, complement)
