What is the probability of obtaining at least 55 red blossomed plants when 75 plants are grown. (The probability of a red plant is .75 or 75%) This may be belong in basic...but I'm not getting any answers there.

Let X be the random variable 'number of red bloosomed plants'.
X ~ Binomial(n = 75, p = 0.75)
Calculate Pr(X > 54).
Yes, but won't I have to calculate it 55 differant times and then add it up? I feel like there is a simple equation for this situation, but it's been a while since I've had stats.
