mel-nik [20]

Asha : 45 - p = 21......this is correct

Jamal : 21 + p = 45....this is also correct

both equations will find the correct solution <==

45 - p = 21 21 + p = 45
-p = 21 - 45 p = 45 - 21
-p = - 24 p = 24
p = 24

An airport has an electronic system that randomly selects bags for extra security screening. Each bag has a 14% percent probabil

Liono4ka [1.6K]

Probabilities are used to determine the chances of an event.

The probability that the two bags are selected for extra screening is 0.02

The given parameters are:

$n = 2$ --- number of bags

$p = 14\%$ --- the probability that a bag is selected for extra screening

The probability that the two bags are selected for extra screening is:

$P(2) = p^n$

So, we have:

$P(2) = (14\%)^2$

Express percentage as decimal

$P(2) = (0.14)^2$

$P(2) = 0.0196$

Approximate

$P(2) = 0.02$

Hence, the required probability is 0.02
