Question

a heterozygous purple flower is crossed with a white flower. what is the chance the offspring will be purple ?​

Answer 1

Predicting Offspring Phenotypes
Only offspring with the bb genotype will have the white-flower phenotype. Therefore, in this cross, you would expect three out of four (75 percent) of the offspring to have purple flowers and one out of four (25 percent) to have white flowers

Hope this helped

Answer 2

assuming that the white offspring are recessive, 50% of the offspring will be purple.
