Answer:17 out of 20
Step-by-step explanation:
Answer:
3(x/4) - 1/2 (x/10) or you can just do 0.7x but I don't think that counts as an expression, so just put 3(x/4) - 1/2 (x/10).
Step-by-step explanation:
Roll the dice 120 times
Number of outcomes from rolling the dice = 6
Probability of 4 falling in 1 roll = 1/6
Probability of the number of 4s in 120 rolls = 120 * 1/6
= 20 times
The probability that 4s falls in 120 dice rolls is 20 times.
Total number of campers = 20
Total number of teams = 5
⇒ Number of campers in each team = Total number of campers ÷ Total number of teams
⇒ Number of campers in each team = 20 ÷ 5
⇒ Number of campers in each team = 4
Number of recorders in each team = 1
⇒ Number of searchers in each team = Number of campers in each team - Number of recorders in each team
⇒ Number of searchers in each team = 4 - 1
⇒ Number of searchers in each team = 3
Hence, there will be 3 searchers in each team
