Answer:
0.0016283
Step-by-step explanation:
Given that:
Proportion of defective bulbs, p = 30% = 0.3
Sample size, n = 19 bulbs
Probability that the lot will pass inspection :
P(none of the 19 is defective) Or P(only one of the 19 is defective)
P(none of the 19 is defective) = (1 - p) ^n = (1 - 0.3)^19 ; 0.7^19
0.7^19 = 0.0011398
P(only one of the 19 is defective) :
P(1 defective) * P(18 not defective )
(0.3) * (1 - 0.3)^18
0.3 * 0.7^18
0.3 * 0.001628413597910449 = 0.0004885
Hence,
P(none of the 19 is defective) + P(only one of the 19 is defective)
0.0011398 + 0.0004885) = 0.0016283
Answer:
Theoretical probability is the likeliness of an event based on all possible outcomes. Theoretically, a coin should land on heads 50 times, and tails 50 times, if you were to flip it 100 times.
Flipping it 60 times would mean theoretical probability would be it landing heads up 30 times, and tails up 30 times.
This actually happening is unlikely though, which is why we also have emperical probability.

Answer:
<u>37 is 15.63% more than 32</u>
Step-by-step explanation:
Let's use the Direct Rule of Three for answering the question correctly:
Number Percent
37 x
32 100
32x = 3,700
x = 3,700/32
x = 115.63 (Rounding to the next hundredth)
115.63 - 100 = 15.63% more
<u>37 is 15.63% more than 32</u>
