Cоnsider the fоllоwing code where the sаme condition vаriаble is used to make threads block in channel_send and channel_receive: 1. enum channel_status channel_send(channel_t* channel, void* data) 2. { 3. pthread_mutex_lock(&channel->mutex); 4. 5. while (buffer_current_size(channel->buffer) == buffer_capacity(channel->buffer)) { 6. pthread_cond_wait(&channel->cond_var, &channel->mutex); 7. } 8. 9. buffer_add(channel->buffer, data);10. pthread_cond_signal(&channel->cond_var);11. pthread_mutex_unlock(&channel->mutex);12.13. return SUCCESS;14. } 15. enum channel_status channel_receive(channel_t* channel, void** data)16. {17. pthread_mutex_lock(&channel->mutex);18. 19. while (buffer_current_size(channel->buffer) == 0) {20. pthread_cond_wait(&channel->cond_var, &channel->mutex);21. }22. 23. buffer_remove(channel->buffer, data);24. pthread_cond_signal(&channel->cond_var);25. pthread_mutex_unlock(&channel->mutex);26. 27. return SUCCESS;28. } Suppose Channel A has a capacity of 1 message and it is currently empty, with no waiting threads in send or receive and the following sequence occurs: Thread 1 and Thread 2 are both created to receive a message from Channel A. These threads start running and block in line 20. The main thread sends a message on Channel A two times. Describe a specific thread ordering using the active threads (i.e., the main thread and threads 1 & 2) that will lead to one thread getting stuck in line 6 and another getting stuck in line 20 forever. You cannot introduce any new threads to the situation, and assume all other channel functions and the usage of these functions are correct.
Accоrding tо а custоmer’s crypto trаnsаction records, 15% of their transactions are Bitcoin sells. If a random sample of 20 transactions was selected, what is the probability that more than 7 of these transactions are Bitcoin sells? Select the appropriate Excel function used to find the probability. General syntax: BINOM.DIST(number_s, trials, probability_s, cumulative)
