Explanation / Answer

Ans:

Total observations=26+17+14+32=89

P(spent money)=(26+14)/89=40/89

P(given four quarters)=(26+17)/89=43/89

P(given one dollar bill)=(14+32)/89=46/89

P(spent money and given four quarters)=26/89

P(spent money and given 1 dollar bill)=14/89

P(spent money/given four quarter)=P(spent money and given four quarters bill)/P(given four quarter bill)

=(26/89)/(43/89)=26/43=0.605

P(spent money/given1dollar bill)=P(spent money and given 1 dollar bill)/P(given1 dollar bill)

=(14/89)/(46/89)=14/46=0.304
