00:01 Hey there, welcome to numerade.
00:03 We are looking at past records that indicate the probability of online retail orders, turning out to be fraudulent.
00:13 So the probability here is expressed as 0 .05, in which we have a sample size here of 22 online retail orders.
00:25 So therefore, we're asked to find a probability for part d, that two or more online retail orders would turn out to be fraudulent.
00:35 So we have the probability that x is greater than or equal to 2...
