Suppose that you randomly draw one card from a standard deck of 52 cards. After writing down which card was drawn, you replace t
KengaRu [80]

Answer:

0.139

Step-by-step explanation:

We are given that

Total number of cards=52

n=18

We have to find the probability of drawing at least 7 spades

Total number of spaded in deck of 52 cards=13

Probability  of getting spade=p=\frac{13}{52}=\frac{1}{4}

Probability,P(E)=\frac{favorable\;cases}{total\;number\;of\;cases}

Probability  of getting no spade=q=1-p=1-\frac{1}{4}=\frac{3}{4}

By binomial theorem of probability

P(X=x)=\binom{n}r}p^rq^{n-r}

P(x\geq 7)=1-P(x\leq 6)

The probability of drawing at least 7 spades=1-\sum_{r=0}^{6}\binom{18}{r}(\frac{3}{4})^{18-r}(\frac{1}{4})^r

The probability of drawing at least 7 spades=0.139
