Answer:
0.083
Step-by-step explanation:
Numbers of Cube = 6
Faces on coins = 2
Therefore, The total outcomes =
Now the favourable outcome that he rolls a 4 & flips a head = 1
The probability that he rolls a 4 & flips a head = 1
=> The probability that he rolls a 4 & flips a head =
Therefore, The probability that he rolls a 4 & flips a head = 0.083
Answer:
The original selling price would be $ 515.87 ( approx )
Step-by-step explanation:
Consider the complete question is :
"A sporting goods store manager was selling a ski set for a certain price. The manager offered the markdowns shown, making the one-day sale price of the ski set $325. Find the original selling price of the ski set. It was marked down 10% and 30%"
Suppose x be the original selling price ( in dollars ),
After marking down 10%,
New selling price = x - 10% of x = x - 0.1x = 0.9x
Again after marking down 30%,
Final selling price = 0.9x - 30% of 0.9x
= 0.9x - 0.3 × 0.9x
= 0.9x - 0.27x
= 0.63x
According to the question,
0.63x = 325
Therefore, the original selling price would be $ 515.87.
