For the spinner above, the probability of landing on black is 1/2, and the probability of landing on red is 1/3. Suppose it is s

Answer:

d) The probability spinner will land on black all three times is 1/8

Step-by-step explanation:

The probability of landing on black = 1/2

The probability of landing on red = 1/3.

Now, if the spinner is spun 3 times.

The probability it will land on black all three times

= $\textrm{ (The probability of landing on black)}^3$

= $\frac{1}{2} \times \frac{1}{2} \times \frac{1}{2} = \frac{1}{2 \times 2 \times 2 } = \frac{1}{8}$

Hence, the probability spinner will land on black all three times is 1/8.

Anvisha [2.4K]

Answer:

Probability will be 0.5779

Step-by-step explanation:

Number of tablets n = 19

Probability of defect rems that is p = 0.03

Here number of trials is fixed and probability of success = 0.03

Here p = 0.03

So q = 1 - p = 1 -0.03 = 0.97

By using binomial distribution

Probability is given by $^nC_rp^rq^{n-r}$

So P(0 or 1) = $^{19}C_0{0.03}^0{0.97}^{19-0}+^{19}C_1{0.03}^1{0.97}^{19-1}=0.5606+0.0173=0.5779$
