The problem uses the concept of Combination where there are number of members chosen from a group and there order is not important. Thus, the expression that would best describe the given above is 30C6 which means the combination of 30 taken 6. The numerical value for this is 593775.
Answer:
The answer is A
Step-by-step explanation:
Answer:
Average = -1°C
Step-by-step explanation:
The data recorded is;
6, -7, -5, 5, -8, 3 (in °C)
Average = = -1°C
55 if you mean one half
5500 if you mean 50 times 110
60 if you mean 50 from 110
Answer:
P(yellow or red) =8/15
Step-by-step explanation:
There are 15 marbles, 3 green, 4 blue, and 5 red marbles.
3+4+5 = 12
That means there are 15-12 = 3 3 yellow marbles.
3 green,
4 blue
5 red
3 yellow
To find the probability of yellow or red, we add the number of yellow and red marbles together over the total number of marbles
P(yellow or red) = (yellow +red)/ total
= (3+5)/ 15
=8/15
