To determine the size of the group of mountain gorillas after the given events, let's break it down step by step:
1. Start with the initial group size of 10 members.
2. After 4 females emigrate, we subtract 4 from the total, leaving us with 10 - 4 = 6 gorillas.
3. With 2 gorillas born, we add them to the current total, resulting in 6 + 2 = 8 gorillas.
4. Lastly, when a male dies, we subtract 1 from the total, giving us 8 - 1 = 7 gorillas.
Therefore, after 4 females emigrate, 2 gorillas are born, and a male dies, the group of mountain gorillas would have 7 members.
I hope this explanation helps you understand how to calculate the size of the group after those specific events! Feel free to ask if you have any more questions.
