Use the "at least once" rule to find the probability of getting at least one 2 in four rolls of a single fair die.
Alexandra [31]

Answer:

Probability of getting at least one 2 equals 0.5177

Step-by-step explanation:

The probability of at least one success is

P=1-(1-p)^{n}

where,

'p' is probability of success of 1 trail

'n' is number of events

We have probability of getting 2 is 1/6 thus 'p' = 1/6

Applying values we get

P=1-(1-\frac{1}{6})^{4}\\\\P= 0.51177
