If you have a bag with 3 red balls and 2 blue balls, what is the probability of drawing two red balls in succession without replacement?

Assuming that the number of accidents that occur in a certain company in a week has a Poisson distribution with a standard deviation of 1.4 . Determine: a) the mean number of accidents that occur in a week b) the probability that in a week, there are no accidents.

Question 6 find \( P(Z<-1.23) \) Add your answer Integer, decimal, or E notation allowed

Two newspapers \( A \) and \( B \) are published in a city. It is known that \( 25 \% \) of the city populations reads \( A \) and \( 20 \% \) reads \( B \) while \( 8 \% \) reads both \( A \) and \( B \). Further, \( 30 \% \) of those who read \( A \) but not \( B \) look into advertisements and \( 40 \% \) of those who read \( B \) but not \( A \) also look into advertisements, while \( 50 \% \) of those who read both \( A \) and \( B \) look into advertisements. Then the percentage of the population who look into advertisement is [JEE (Main) 2019] \( \begin{array}{ll}\text { (a) } 12.8 & \text { (b) } 13.5 \\ \text { (c) } 13.9 & \text { (d) } 13\end{array} \)

Question 19 In a survey, 46\% of Americans say they suffer great stress at least once a week. If three people are selected at random, what is the probability that all three will say that they suffer great stress at least once a week? Add your answer Integer, decimal, or E notation allowed

Question 2 The speeds of cars are measured using a radar unit, on a motorway. The speeds are normally distributed with a mean of \( 90 \mathrm{~km} / \mathrm{hr} \) and a standard deviation of \( 10 \mathrm{~km} / \mathrm{hr} \). What is the probability that a car selected at chance moves at more than \( 100 \mathrm{~km} / \mathrm{hr} \) ? Add your answer Integer, decimal, or E notation allowed
