Answer to Problem 4CYU
The required probability is 0.20
Explanation of Solution
Given information:
The number of red flowers if 4 seeds are planted
Calculation:
Following table show the given relative frequency graph in the table format
Number of flowers, R | Relative frequency, P(R=r) |
0 | 0.2 |
1 | 0.45 |
2 | 0.2 |
3 | 0.1 |
4 | 0.05 |
Total | 1 |
(a)
The required probability is,
Hence, required probability is 0.20
b
To calculate: the probability that at least 2 are red flowers
b
Answer to Problem 4CYU
The required probability is 0.35
Explanation of Solution
Given information:
The number of red flowers if 4 seeds are planted
Calculation:
(b)
The probability that at least 2 are red is,
Hence, required probability is 0.35
c
To calculate: If the ten pots are planted with 4 seeds each, then probability to expect 1 red flower
c
Answer to Problem 4CYU
The required probability is 4.5
Explanation of Solution
Given information:
The number of red flowers if 4 seeds are planted
Calculation:
(c)
The probability of one red flower is
So, expected number of pots out of 10 having 1 red flower is
Hence, required probability is 4.5
