A cell phone company orders 400 new phones from a manufacturer. If the probability of a phone being defective is 2.1%, predict how many of the phones are likely to be defective. Round your answer to the nearest whole number.
I'm really sorry but I need help this is due today and it's also my birthday and I'm supposed to be spending time with my family but I need the answer to a couple questions.
No worries! I'm here to help you. To predict how many of the phones are likely to be defective, we can use the concept of probability.
First, we need to find the number of defective phones out of the 400 ordered. To do this, we can multiply the probability of a phone being defective (2.1% or 0.021) by the total number of phones ordered (400).
Defective phones = Probability of being defective × Total number of phones
Defective phones = 0.021 × 400
Defective phones = 8.4
However, since we are rounding to the nearest whole number, we round 8.4 to the nearest whole number, which is 8.
So, based on a probability of 2.1%, we can predict that approximately 8 out of the 400 phones ordered are likely to be defective.
400*.021 = ?
Happy Birthday!
