Someone i failed this on plato 10 times i need the correct answer round your answers to the nearest thousandth. the probability that sandra gets a ride to work on any morning is 0.7. the probability that she gets a ride 3 times in a 5-day work week and the probability that she gets a ride at least 2 times in a 5-day workweek

Step-by-step explanation:

For all Plato users

The probability that she gets a ride 3 days in the week is 0.309.  The probability that she gets a ride to work at least 2 times in the week is 0.969.

This is binomial, as there are two outcomes, the probability of one happening does not affect the other, and there is a fixed number of trials.

For three rides to work that week,


To find the probability that she gets a ride at least twice that week, we first find the probability that she does not get a ride at all that week or she only gets a ride one day; then we subtract that from 1:

Yeah she/ he needs look how long that is man
