There are 24 red, 34 white , 18 blue and 28 pink gumballs in the gumball machine. Sharie wants to get a blue or pink gumball.

Use / for fraction bar if necessary

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! : )

the mistake in the pattern is that :

b. the decimal point was moved one too many place values each time

the correct pattern could be made by :

b. moving the decimal point to the right the same numbers of place values as the exponents

to find the total number of combinations, multiply the quantity of each item by each other:

2 pairs of shoes x 3 pairs of shorts = 6 different combinations.
