Question

one card is drawn and replaced 250 times. how many times would you expect the yellow - flower card to be drawn? ? times

Explanation:

Step1: Calculate probability of drawing yellow - flower card

There are 5 cards in total and 3 are yellow - flower cards. So the probability $P$ of drawing a yellow - flower card in one draw is $P=\frac{3}{5}$.

Step2: Calculate expected number of draws

The number of trials $n = 250$. The expected value $E$ of the number of times a yellow - flower card is drawn is given by $E=n\times P$. Substitute $n = 250$ and $P=\frac{3}{5}$ into the formula: $E = 250\times\frac{3}{5}=150$.

Answer:

150
