Answer:
Mark brainliest pls
Step-by-step explanation:
People have given you correct answers but not explained why, perhaps because it seems so obvious.
One of Bayes laws of probability says that if two events e1 and e2 are independent (unrelated), then the probability of both happening together is the product of their individual probabilities.
The die and the coin are independent events. Each is a 50% chance (odd number on a die, heads on a coin). Thus the probability of both happening together is 50% * 50% = 25%.

Answer:
£480
Step-by-step explanation:
x = the original price of a computer
£x = 100% of the original price
The price of a computer was decreased by 30% to £336.
This means:
£336 = 100% - 30%
£336 = 70% of the original price
From this, we will find 1% of the original price.
£336 ÷ 70 = 1%
£4.8 = 1%
Since the original price ( x ) = 100% of the original price, we will find 100% of the original price.
£4.8 × 100 = 100%
£480 = 100%
Therefore, the original price of a computer = £480

Answer:
x = -1
Step-by-step explanation:
Given
(x - 5)(-3) = 18
Expand the bracket
x X -3 -5 x -3 = 18
-3x + 15 = 18
Subtract 15 from both sides
-3x + 15 - 15 = 18 - 15
-3x = 3
Divide both sides by -3
-3x/-3 = 3/-3
x = -1
