Answer:

100%

Explanation:

We are given a red flower plant. This means its homozygous dominant (RR). We are given a white flower plant. This means it is homozygous recessive (rr). Each plant will give its allele. The red one will always give R and the white one will always give r. Heterozygous (Rr) plants have pink flowers. So they will all be pink.
