Answer:

c. sin 8x + sin 2x

Step-by-step explanation:

1. Convert the product into sum or differences: 2 sin 5x cos 3x

Solution:

2 sin 5x cos 3x = sin (5x + 3x) + sin (5x -3x), [Since 2 sin A cos B = sin (A + B) + sin (A - B)]

= sin 8x + sin 2x

Which event has a probability other than 1/2?
Vadim26 [7]

Answer:

Option B.

Step-by-step explanation:

In the given events lets find out the event that has a probability other than 1/2.

A. Flipping a coin gives result of head or tail, so the probability of the result of tails is 1/2.

B. Choosing a vowel from a bag of tiles that contains one of each letter of the alphabet, so the probability of choosing vowel is 5/26.

C. A cube that has numbered from 1 to 6, there are 3 even numbers and 3 odd numbers, so the probability of rolling even number is 3/6 or 1/2.

D. There is 26 red cards in a standard deck of 52 cards, so the probability of choosing red card is 26/52 or 1/2.

Therefore, events A, C and D gives result of 1/2 and B other than 1/2

So Option B is the correct answer.
