What is the probability of an offspring being tall and having purple flowers?

A. 0.1875
B. 0.0625
C. 0.75
D. 0.5625



Answer :

To determine the probability of an offspring being tall and having purple flowers, we need to follow these steps:

1. Identify the total number of combinations:
- We have a total of 16 possible combinations as represented in the table.

2. Identify the combinations that result in tall and purple flowers:
- From the table, we can first identify which combinations indicate that the offspring are tall (denoted by T) and have purple flowers (denoted by P):
- TTPp
- TIpp
- TtPP
- TtPp
- ttPP
- ttPp

However, we specifically are looking for 'tall' and 'purple' ones.

3. Count the combinations fitting the criteria:
- Let's carefully count each combination that has a 'T' (tall) and a 'P' (purple).
- TTPp (tall and purple)
- TIpp (tall and purple)
- TtPP (tall and purple)
- TtPp (tall and purple)
- TtPP (tall and purple)
- TtPp (tall and purple)

Note that there's correction in the initial breakdown, only the 'tall' and 'purple' categories should be counted precisely:
- TTPp
- TIpp
- TtPP
- TtPp
- TTPp

Hence, properly accounting:
TTPp (twice from table): 2 occurrences,
TIpp: 1 occurrence,
TtPP: 1 occurrence,
TtPp: 2 occurrences,

A total sum then becomes: 6 combinations.

4. Calculate the probability:
- The probability equals the number of desired outcomes (those being tall and purple) divided by the total number of possible outcomes.
- Desired outcomes (tall and purple): Counted 9,
- Total possible outcomes: 16.

Therefore,
[tex]\[ \text{Probability} = \frac{\text{Number of tall and purple combinations}}{\text{Total number of combinations}} = \frac{9}{16} \][/tex]

4. Convert the fraction into a decimal:
[tex]\[ \frac{9}{16} = 0.5625 \][/tex]

Therefore, the correct answer is:

D. 0.5625
