## How do you find the least probability?

Lastly, the probability that at least one student prefers math is calculated as: P(at least one prefers math) = 1 – P(all do not prefer math) = 1 – .

Solution:

1. P(makes at least one) = 1 – P(misses a given attempt) n
2. P(makes at least one) = 1 – (0.80)
3. P(makes at least one) = 0.672.

How do you do at least 2 probability?

n: number of trials. k: number of successes. p: probability of success on a given trial.
Next, let’s plug these values into the following formula to find the probability that he answers at least two questions correctly:

1. P(X≥2) = 1 – P(X=0) – P(X=1)
2. P(X≥2) = 1 – 0.01024 – 0.0768.
3. P(X≥2) = 0.91296.
