There are 1200 elephants in a herd. some have pink and green stripes, some are all pink and some are all blue. one third are pure pink. is it true that 400 elephants are definitely blue? why?

Yes.

The remaining 2/3 elephants left could be a mix of blue and green shared equally.

Step-by-step explanation:

Total number of elephants= 1200

Number of possible colours=3 (blue,green and pink)

Number of pink elephants =1/3 of 1200

Number of pink elephants =1/3×1200

Pink elephants are 400

The remaining fraction will b 1-1/3=2/3

Total number of elephants - number of pink elephants = remaining number of elephants => 1200-400=800

A 12

Step-by-step explanation:

the total amount of boys on the chart are 35 and 23 are already marked on the super slide, so that means that there are 12 people marked as the Ferris wheel because 35-23=12
