Answer:
p(blue gumball)=18/104=9/52
p(pink gumball)=28/104=7/13
p(blue or pink gumball)=42/104=21/52
p(not blue or pink gumball)=58/104=29/52
Step-by-step explanation:
p(blue gumball)= number of blue gumballs/total number of gumballs
p(pink gumball)= number of pink gumballs/total number of gumballs
p(blue or pink gumball)= number of blue+number of pink/total number of gumballs
p(not blue or pink gumball)= you could think of this two ways, either subtract the number of blue+pink gumballs from the total number of gumballs; 104-(18+28)=58/104
or, just add up the gumballs that are not blue or pink (the red and white ones) and divide that by 104;
(24+34)/104=58/104
hope this made sense! : )
